Fill in the blanks with correct options :
Question 1.
Britain did not depend on different parts of the world for ________ and ________ (labourers; raw material; capital; inventions)
Answer:
labourers, capital

Question 2.
Two important types of transport during the Industrial revolution were ________ and ________ (road, air, water, rail)
Answer:
water, rail

Question 3.
Write two sentences each on following aspects in the context of Industrial revolution:
a) Technology
b) Financing and money
c) Agriculture revolution
d) Transport systems
Answer:
a) Technology :
The commencement of industrial revolution is closely linked to a small number of innovations, beginning in the second half of the 18th century. By the 1830s the following gains had been made in important technologies, e.g. : Textiles, steam power and iron making.

b) Financing and money:
The whole industrial revolution got founded by a few people who held power to issue essentially infinite credit. Most new industries were financed by small investors, merchants, shopkeepers and farmers.

c) Agriculture Revolution :
The Agriculture Revolution was period of agriculture development between 18th and the end of 19th century, which saw a massive and rapid increase in agricultural productivity and vast improvement in farm technology. Many inventions were created and improved during this revolution.

d) Transport Systems :
The growth of industrial revolution developed on the ability to transport raw materials and finished goods over long distances. These facilities were of three main types – Water ways, Roadways and Rail roads.
Out of these three, water transportation was the cheapest.

Question 4.
What do you think is special about inventions happening during the industrial revolution ?
Answer:

• Most inventions were more the product of determination, interest, curiosity, even luck, than the application of scientific knowledge.
• Some inventors in the cotton industry, like John Kay and James Hargreaves, were familiar with the skills of weaving and carpentry.
• Richard Arkwright, however, was a barber and wig-maker, Samuel Crompton was not technically skilled and Edmund Cartwright studied literature, medicine and agriculture, initially wished to become a clergyman and knew little of mechanics.
• By contrast, in the area of steam engines, Thomas Savery, an army officer, Thomas Newcomen, a blacksmith and locksmith, and James Watt, with a strong mechanical bent, all had some knowledge relevant to their inventions.
• The road-builder John Metcalf, who personally surveyed surfaces for roads and planned them, was blind.
• The canal builder James Brindley was almost illiterate, with such poor spelling that he could never spell the word ‘navigation’, but he had tremendous powers of memory, imagination and concentration.

Question 5.
How were the lives of different classes of British women affected by the Industrial revolution?
(OR)
“All classes of British women were affected by the industrial revolution” Write your comments.
Answer:

• The Industrial Revolution was a time of important changes in the way that women worked.
• The village women were actively involved in farm work, they reared livestock, gathered firewood and spun yarn on spinning wheels in their homes.
• Their earnings were necessary to supplement men’s meagre wages.
• Women were the main workers in the silk, lace making and knitting industries, as well as in the metal industries of Birmingham.
• Women may well have gained increased financial independence and self-esteem from their jobs; but this was more than offset by the humiliating terms of work they endured.
• Most classes eventually benfited in some way from the huge profits.
  Thus the lives of different classes of British women were affected by the industrial revolution.

Question 6.
What were the relative advantages of canal and railway transportation?
Answer:

• It is easy to shipping goods.
• Both are cheap means of transport when compared to roadways.
• Bulk quantity of goods can be transhipped.

Question 9.
Read the para under the title “The workers” of Page No. 192 and comment on it.

The Workers : A survey in 1842 revealed that the average lifespan of workers was lower than that of any other social group in cities: it was 15 years Birmingham, 17 in Manchester, 21 in Derby. More people died, and died at a younger age, in the new industrial cities, than in the villages they had come from. Half the childern failed to survive beyond the age of five. The increase in the population of cities was because of immigrants, rather than by an increase in the number of childern born to families who already lived there. Deaths were primarily caused by epidemics of disease that sprang from the pollution of water, like cholera and typhoid, or of the air, like tuberculosis. More than 31,000 people died from an outbreak of cholera in 1832. Until late in the nineteenth century, municipal authorities were negligent in attending to these dangerous of life. The medical knowledge to understand and cure these diseases was unknown.

(OR)

A survey in 1842 revealed that the average lifespan of workers was lower than of any other social group in cities

Q: “What were the problem faced by workers in those days”. Comment it.
Answer:

• The life of the workers was hard.
• Multiple families were living in one apartment.
• Very poor sanitary conditions in the factories and in houses.
• No enough earning to buy basic needs.

Question 1.
Write two important inventions which revolutionised the textile industry. (Text Book Page No. 188)
Answer:

1. Water powered loom – Edmund Cartwright.
2. Spinning Jenney – James Hargreaves.

Question 2.
Mention two important industrialisation effects on women and children’s life. (Text Book Page No. 193)
Answer:

• Women lost their family life and children their childhood.
• Women had gained increased financial independence and self-esteem. Children worked in factories and stayed away from education.

Question 3.
Compare the industrialisation in Germany and France. Identify similarities and differences. (Text Book Page No. 195)
Answer:
Similarities :

• Germany and France lacked colonial resources.
• In both the countries industrialisation received a boost by the introduction of.railways in 1830s.
• Railways stimulated trade, communication and economic growth.

Differences :

Germany	France
1) German industrialisation was greatly facilitated by the German government.	1) France, in contrast, was slow in industrialising.
2) The needed heavy capital investment was received from large banks.	2) France did not develop banks which could mobilise large amount of capital and lend them to industrialists.
3) Market facilities were provided on large scale.	3) Market facilities were provided after 1860.
4) Germany gained back her coal mines.	4) France lost her coal mines to Germany.
5) The industrial units were very large.	5) The units were run at homes only.

Question 4.
Discuss the developments in Britain and in other parts of the world in 18th entury that encouraged British Industrialisation. (Text Book Page No. 187)
Answer:

• The Industrial Revolution took place in Great Britain almost a century before any other country.
• At that time Great Britain was a very powerful country that controlled many colonies.
• The country gained abundant useful resources from these colonies that aided its growth.
• The country had also just experienced an Agriculture Revolution.
• The country could support the demand for workers in factories. It has many natural resources.
• During the Industrial Revolution, the government of Britain was stable, wealthy and supportive of economy growth. So the Industrial Revolution was emerged first in Great Britain.
• The Industrial Revolution on continental Europe came a little later than in Great Britain, this involved the application of technology developed in Great Britain in new places. Often the technology was purchased from Britain or British engineers and entrepreneurs moved in search of new opportunities.
• The German, Russian and Belgian governments also provided state funding to the new industries.
• France’s economic growth industrialisation process was slow and steady along the 18^th and 19^th centuries.
• U.S. also supported Industrial Revolution and provided fuels for economic and industrial growth.
• Japan : There Industrial Revolution began about 1870 as Meiji period leaders decided to catch up with the west.

Question 5.
Discuss the effects of early industrialisation on British towns and villagesandcompare these with similar situation in India. (Text Book Page No. 194)
Answer:
New technology and techniques in agriculture paved the way for change. As surplus of cheap agriculture labour led to serve unemployment and rising poverty in many rural areas. As a result, many people left the countryside to find work in towns and cities. So the scene was set for a large scale labour intensive factory system. It led to urbanization.

In India during colonial rule, the British exported all the raw material to Britain. They did not establish or develop any industry here. They did not encourage the agriculture. They imported the finished goods. Both the agriculture and cottage industries were disturbed. As the agriculture is the backbone of India, the dependants suffered a lot. The dependants on agriculture became cheap labour.

Question 6.
What factors enabled Germany to outstrip England and France in industrialisation? (Text Book Page No. 195)
Answer:
The factors that enabled Germany to outstrip England and France in industrialisation:

1. Its government assistance.
2. Transport facilities.
3. The governments’s control over working class, movement with a heavy hand.
4. The government provided for many social benefits and insurance for the workers.
5. Benefit from the technical developments achieved by Britain and U.S.A.
6. Heavy capital investment facilities from large banks.
7. A great proportion of Germany’s industrial production was used to build up Germany’s military and naval power.

Question 7.
Why is high quality steel and iron necessary for industrialisation? Discuss in the class. (Text Book Page No. 188)
Answer:
Throughout the 18 and 19 centuries the English steel and iron makers produced blister and crucible steel and iron. In the 18th century innovations like steam boats, rail road and guns increased the demand for fine iron and steel.

Question 8.
Why do you think the mining of iron ore and coal received equal importance? (Text Book Page No. 188)
Answer:
I think coal is used for smelting iron. So the mining of iron ore and coal received equal importance.

Question 9.
Why do you think the early industrial centres were situated near the iron and coal mines? (Text Book Page No. 188)
Answer:
I think there were no proper transportation facilities to transport the coal and iron. And it is very difficult also to transport such heavy things from one place to another place. Later the canal and rail road transports were introduced and developed. So the early industrial centres were situated near the iron and coal mines.

Question 10.
Why do you think France lagged behind in industrial development? (Text Book Page No. 195)
Answer:
France was slow in industrialising. Even by the end of 19^th century she remained a rural country with a large majority of people cultivating small plots of land. Manufacturers found it more profitable to give out work to rural workers who worked at home rather than to set up factories in towns. Such rural domestic production began to decline after 1850 resulting in economic adversity for the people. Machines in towns began to take over much of the work and only delicate hand work was given out to rural workers. Much of French industrialisation was a result of the spread of railway and road networks after 1860 which created a wide market for its industrial goods.

France also did not develop Banks which could mobilise large amount of capital and lend them to industrialists. As a result most of French manufacturers depended upon family resources. They remained small companies as a result. It also made them slow in adopting new ideas and technologies.

Heavy industry based on iron and coal was slow to develop in France as she did not have good reserves of coal and depended upon expensive imports. Thus French industrialisation remained focused on consumer products like textiles, which were basically small scale enterprises. This was in contrast to the German and British Industrial situation where heavy industries predominated.

So France lagged behind industrial development.

Question 11.
What were the difficulties faced by women and children during industrial revolution? (Text Book Page No. 186)
(OR)
What are the difficulties faced by Women and Children during industrial revolution? What is your reaction towards this?
Answer:
The following selections are testimonies from England and Wales collected by Parliamentary Commission who began to investigate the industrial employment of women and children in the early 1840s.

1. Working conditions were unsanitary and the work was dangerous.
2. Education of the children suffered because of the demands of work.
3. Home life suffered as women were faced with the double burden of factory work formed by domestic chores and child care.
4. Men assumed supervisory roles over women and received higher wages.
5. Unsupervised young women away from home generated societal fears over their fate.
6. As a result of the need for wages in the growing cash economy, families became dependent on the wages of women and children.
7. There was some worker opposition to propagate that child and female labour should be abolished from certain jobs.
8. Children as young as 5 years old worked hard hours for little or no pay (sometimes 19 hours a day)
9. Large, heavy and dangerous equipment was very common for children to be using or working near.
10. Many accidents occurred injuring or killing children on the job.

My reaction :
This is very cruel and inhuman treatment. If it is there now-a-days the factory owners should be punished by govt severely.

Question 1.
Fill in the blanks.
a) Hydrosphere is related to ………………………
b) Lithosphere is related to ………………………
c) Atmosphere is related to ………………………
d) Biosphere is related to ………………………
Answer:
a) water mass
b) landmass
c) air mass
d) life

Question 2.
Find the odd one out in the context of lithosphere and give reasons for your choice.
Byson gorge; Grand Canyon; Ozone; Thar desert.
Answer:
Out of these four ozone is the odd one.
Reasons:

1. Byson gorge and Grand canyon are hilly areas.
2. Rivers flow through them.
3. Plants and trees are present there.
4. Thar desert is a vast sand desert, with no water. It has thorny bushes and some kinds of desert plantations.
5. Above three are landforms.
6. But Ozone is an inorganic molecule with the chemical formula 03. It is a pale blue gas with a distinctively pungent smell. Ozone’s 03 formula was determined in 1865.

Question 3.
How is the Lithosphere formed?
Answer:

• The solid crust or the hard top part of the earth is called lithosphere.
• The crust is made up of rocks and minerals and covered with a thick layer of soil.
• It is uneven and has high mountains, plateaus, plains, and very deep basins.
• Many of these features are shaped by internal and external processes.
• The slow movements inside the earth lead to the formation of the crust.
• The sudden movements can damage and lead to changes in landforms.
• The processes originating from the depths of the earth like earthquakes and the volcanic eruptions play important role in shaping the surface of the earth.
• The external sources like wind, water, glaciers, and waves also play prominent role in shaping the lithosphere.

Question 4.
How are the continental plates formed and how are they eventually destroyed?
Answer:

• In the beginning, probably all continents were held together.
• Later the earth’s lithosphere is broken up into several pieces, just like the pieces of a large jigsaw puzzle and thus continental plates formed.
• These pieces, on which all the continents and oceans are actually situated, are called “Plates”.
• They float on soft layer of the mantle.
• There are about seven major plates and several minor plates on the earth.
• As the plates move, they push, pull, slide, rise, sink, bend and break.
• Sometimes one plate meets another, the incoming plate dips under the stable plate.
• In fact the incoming plate actually goes into the mantle of the earth and becomes molten due to the heat of the mantle.
• That is how some plates are eventually destroyed.

Question 5.
List out the landforms formed due to the river work. (AS1)
Answer:
Many landforms are formed due to the work of the river. They are
1. V – shaped valley:
The flow of a river is very swift as it descends the steep slopes and it exerts a great force in cutting the mountain vertically. As a result a deep valley develops, narrow at the bottom and wide at the top. This is called V – shaped valley.

2. Gorge:
Where the rocks are very hard, the river cuts a narrow valley with steep sides called Gorges.

3. Canyon:
A deep valley with steep like slopes and is wider at its top than at the bottom is called a Canyon.

4. A plunge pool:
The water falls with great force and dig out the rock beneath to form a plunge pool.

5. Plain:
When the river is in floods it cuts the soil and when it is not in flood it deposits silt and thus forms vast flood plains.

6. Meanders:
As a result of the deposition by floods the river bed becomes too high, the river constantly changes its course and cuts new path and forms gentle snake like meanders.

7. Ox-bow lakes:
Due to the deposition along the sides of the meanders, the ends of the meander loop comes closer and closer. In the course of time the meander loop cuts off from the river and forms a cut off lake which is called ox-bow lake.

8. Delta:
When a river reaches the sea, the fine material is deposited at its mouth forming a delta (∆).

9. Ozone:
Ozone is an inorganic molecule with the chemical formula 03. It is a pale blue gas with a distinctively pungent smell. Ozone’s 03 formula was determined in 1865.

Question 6.
Create a table as given below and fill information. And write a small paragraph to explain the similarities and differences you can think of in the context of earth’s external changes, (if there is no information available in the text, leave those columns blank)

	Wind	Water	Glacier
Landform
Process

Answer:
Wind:
Wind takes many forms and carries away the surface of the land in the higher places.

Water :

1. Water reacts with the chemicals of the rocks and further weakens the rock.
   Water acts as moving agent of the earth.

Glacier :

1. The ice on these glaciers melt throughout the year and flows to low areas as rivers and streams.
2. They also erode, transport and deposit rock materials.

Two forces, weathering and erosion, are constantly at work building up and moving rocks making up the earth’s crust.

Weathering causes rocks to fragment, crack, crumble, or break down physically and chemically.

Erosion loosens and carries away the rock debris formed by weathering. Over time these two forces, working together, change the shape of the land.

Question 7.
Why are Glaciers not found in your surroundings?
Answer:
Glaciers are most commonly found above snow line i.e., regions of high snow fall in winter and cool temperatures in summer. These conditions allow more snow to accumulate on the glacier in the winter that will melt in the summer. This is why most glaciers are found either in mountainous areas or the polar regions.

We are in the state of Andhra Pradesh. It is a semi-arid area and has a predominantly hot and dry climate. Summers start in March, and peak in May with average high temperatures in the 42°C range. A dry, mild winter starts in late November and lasts until early February with little humidity and average temperatures in the 22°C – 23°C range. In such hot and dry conditions glaciers are not formed. So we cannot find glaciers in our surroundings.

Question 8.
How are Beaches formed and name some Beaches?
Answer:
Formation of Beaches:

1. Sea water contains sediments like sand, pebbles, etc.
2. Beaches form as waves deposit these sediment on the shore.
3. The wind pushes these sediments on the shore and inland.
4. This creates an area of sand particles finally form a beach.

Names of some beaches :

1. Diu Beach
2. Manori Beach, Mumbai
3. Versova Beach, Mumbai
4. Mivamar Beach, Panaji
5. Karwar Beach, Karnataka
6. Fort Kochi, Cochin
7. Kovalam Beach, Trivandrum
8. Marina Beach, Chennai
9. R.K. Beach, Visakhapatnam
10. Chandipur Beach, Odisha.

Question 9.
How is the human lifestyle responsible for extension of deserts?
Answer:

• Desertification can be considered as a set of biological, chemical, and physical processes which converge to create desert-like conditions.
• Desertification is a social problem involving people at all stages as a cause and as victims.
• The anthropogenic (human) causes of desertification are over cultivation, over grazing, deforestation and poor irrigation practices.
• These factors are fuelled by local forces such as poverty and population pressure.
• Increase in temperature leads to drying out of water and it further causes to expansion of deserts.
• Mismanagement of dry land ecosystems by humans can cause desertification.
• Poor land use and overgrazing are significant factors for the expansion of deserts.
• Thus activities of human beings lead to the extension of deserts.

Question 10.
Find out the order of the landforms for the following.

Landform	Order of Landform
The Himalayan Mountains	II order Landform
The Pacific Ocean
Asia Continent
Byson Gorge
Jog waterfall
Rocky mountains
The Indian Ocean
The great rift valley

Answer:

Landform	Order of Landform
The Himalayan Mountains	II order Landform
The Pacific Ocean	1 order Landform
Asia Continent	1 order Landform
Byson Gorge	III order Landform
Jog waterfall	III order Landform
Rocky mountains	II order Landform
The Indian Ocean	1 order Landform
The great rift valley	III order Landform

Question 11.
Draw the map of world plates by observing map 2.
Answer:

Question 12.
Read the para under the title ‘Erosion’ on page 20 and comment on it.

Erosion : Flowing water and wind have great power and can slowly wear away or cut away the rocks and soil cover in higher places. Water acts in many ways, as rain, river, flowing ground water, sea waves, glaciers etc. Wind too takes many forms like storms, gusts, steady winds, etc. The active wearing away of the earth’s surface by these moving agents is called erosion.

Answer:
Erosion is the process by which soil and rock are removed from the earth’s surface by exogenic processes such as wind or water flow, and then transported andsdeposited on their locations while erosion is a natural process. Human activities have increased by 10 – 40 times the rate of which erosion is occuring globally.

Question 13.
Collect newspaper or magazine articles and news on earthquakes and volcanoes.
Prepare an illustrated file on these – how do they happen and how they affect human life.
Answer:
Student’s activity.
Ex: Earthquakes:
The earth’s surface is formed of massive slabs of rock called plates. These are called tectonic plates, are always moving. Sometimes they just slide past one another. At another time they actually collide with one another. Plate movements cause the build up of tremendous quantities of energy in the rock. When the energy is released, it produces vibrations that travel through the rock, leading to earthquakes. During earthquakes, faults, or giant cracks, are produced by the pressure of moving rocks.

Volcanoes:
Deep within the earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Because it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually some of the magma pushes through vents and fissures in the earth’s surface. Then a volcanic eruption occurs.

Their effect on human life :

1. Major earthquakes and volcano eruption can affect human life.
2. Roads can be damaged and delivery of food can be disrupted.
3. Clean, drinking water may not be available.
4. Sewer system may leave, causing diseases.
5. Gas line could leak, causing health issue.
6. All the surroundings can get covered with ash.
7. Communication system fails.
8. They destroy property and threaten human lives.

9th Class Social Studies 2nd Lesson The Natural Realms of the Earth InText Questions and Answers

Question 1.
Why do you think the rock is harder inside than outside? (Text Book Page No. 20)
Answer:

• The gradual disintegration of rocks is caused by atmosphere forces.
• The rocks when exposed to heat expand and contract when cooled down.
• As surface rock contracts and expands and contracts again, it gradually becomes brittle and begins to break down.
• Water reacts with the chemicals in the rock and further weakens it.
• These processes by which the rocks are weakened and broken are called ‘weathering’.
• It is easier to chip small pieces of rock from the outer layer rather than from the core of the rock.
• Thus we can say the rocks are harder inside than outside.

Question 2.
Expalin how are the waterfalls are useful. (Text Book Page No. 22)
Answer:

• The most noted advantage of waterfalls is their ability to produce hydroelectric power.
• As it descends the steep slopes the waterfall exerts a great force and cuts mountains vertically and forms V-shaped valleys, gorges and canyons.
• These attract many tourists throughout the world and earn a lot of foreign exchange.
• Waterfalls put oxygen into the water which first helps the fish breathe well.

Question 3.
Can you discuss in the class how the following human actions impact the lithosphere?
i) Mining
ii) Building cities with bricks and cement
iii) Agriculture
iv) Dams (Text Book Page No. 25)
(OR)
‘Human actions like mining, building cities with bricks and cement, agriculture and dams are impacting the lithosphere’ – Comment on it. Mra
Answer:
i) Impact of mining on lithosphere :

• Mining disturbs and removes the rocks, ores and minerals in the geosphere.
• It leaves huge gaping holes in the earth.
• The mine tailings are pulled up in large mounds on the surface of the geosphere.
• Subsidence is an effect that occurs above a deep mine.
• The deep mines cause redistribution of the existing tectonic stress field disturbed by the excavation process.
• High stresses exist inside tectonic plates and they are sensitive to any perturbations.
• In case of mining the mass removal causes fault zones and eventually earthquakes.

ii) Impact of building cities with brick and cement on lithosphere:
Constructing buildings with cement and bricks has a lot of negative effects.

• Concrete used to create hard surfaces causes to surface turn off and it can cause heavy soil erosion.
• Constructing the buildings with cement, bricks and concrete have different thermal and hydrological properties. These cause the surface absorbs and stores heat and water.

iii) Impact of agriculture on lithosphere:
Man has been trying to manipulate more and more of nature and exploit this natural resource by the unscientific practice of agriculture.

• Agriculture causes the depletion of underground acquifiers through overdrafting.
• Under irrigation gives poor soil salinity control which leads to increase soil salinity with consequent build up of toxic salts on soil surface.
• Wide use of agricultural chemicals causes soil pollution.

iv) Impact of dams on lithosphere :

• As a result of dam construction and holding of sediments in reservoirs sediment feeding of down stream channel or shore beaches is prevented.
• Corrosions may occur.
• Rare archaeological and historical places with their exceptional beauties disppear after lying under the reservoir.
• Earthquakes and volcanic activity can be induced by the weight of the reservoir on nearby faulty lines.
• Soil erosion of silt deposited at the edges of reservoirs can seriously damage surrounding vegetation and farmland by sand blow.

Question 4.
Write an imaginary description of the damages that occur due to volcanic eruption in an area. (Text Book Page No. 19)
Answer:

• Volcanic eruption can cause earthquakes, fast floods, mudslides and rock falls.
• Lava can travel very far and burn, bury or damage anything in its path including people, houses and trees.
• The large amount of dust and ash can cause roofs to fall, makes it hard to breathe and is normally very smelly.
• The ground around volcano is not secure and can cause big earthquakes.
• Big volcanic eruptions can change the weather around the world.
• Ash clouds float very high in the air and can cause snow and frost in the summer in a lot of countries.

Question 5.
Compare the Loess Plains with a Delta. What similarities and differences do you see between them? (Text Book Page No. 25)
Answer:
Similarities between Loess Plains and Deltas :

1. Both are the deposits of erosional fine materials on plains.
2. Both loess plains and deltas are fertile lands.

Differences between Loess Plains and Deltas:

1. While loess plains are formed with fine dust blown beyond the deserts, the deltas are formed with fine alluvial material transported by the rivers.
2. While loess plains are formed in the neighbouring lands of the deserts, the deltas are formed at the mouths of the rivers.
3. While loess are fine loam, rich in lime, very coherent and extremely porous, the deltas consist of clayey alluvial soils with a mixture of organic material.
4. While deltas are formed by the action of rivers, the loess plains are formed by the action of winds.

Question 6.
Geologists have found fossils of sea animals on the Himalayas. Some of these are actually worshipped in many homes as ’Salagramas’. How do you think are these^ossil^here on the Himalayas? (Text Book Page No. 17)
Answer:

• The Himalayas are formed by the collision of the Indian and Eurasian land masses which were originally separate.
• This collision uplifts mountains.
• From around 200 million years ago the area between the two separate land masses was covered by the Tethys sea, which was filling with sediments and had sea creatures which left fossils in the sedimentary rocks formed there.
• So the fossils found in the Himalayas are those formed in the ancient sea bed of the Tethys sea, now exposed and pushed up to form mountains.
• Salagramas are usually black coloured spherical fossils found in the sacred river Gandaki.
• The name salagrama refers to the name of the village on the bank of the Gandaki, where the holy stones are picked up.
• Hindus consider these salagramas as an iconic representation of Vishnu and worship these salagramas.

Question 7.
Collect information about the waterfalls in Andhra Pradesh. (Text Book Page No. 22)
Answer:
Waterfalls of Telangana :

1. Ethipothala falls, near Nagarjuna Sagar Dam.
2. Katiki waterfalls – Visakhapatnam district
3. Kailasakona falls – Chittoor district

Question 9.
Gorges are suitable for construction of dams- can you tell why this is so? (Text Book Page No. 21)
Answer:

• Gorges are narrow valleys with steep sides.
• A gorge is almost equal in width at its top as well as its bottom.
• They are suitable for the construction of massive reservoirs.
• The natural valleys formed by the gorges are built up with hard rock.
• The valleys with its steep sides, extensive rocky floors form the natural reservoirs for the dams.
• Constructing the dams at gorges is less expensive because a little concrete work is needed to form the reservoirs.
• In these vast and massive reservoirs a lot of water can be stored.
• Gorges are flood proof. They prevent floods.
• The waterfalls that falls down from great heights into the gorges can rotate large turbines and generate hydroelectricity in large quantities.
• Thus gorges are suitable for the construction of dams.

Question 10.
You have read about mining of minerals like baryte or coal. In what ways do you think does mining affects the lithosphere, hydrosphere and atmosphere? (Text Book Page No. 14)
Answer:

• Mining disturbs and removes the rocks, ores and minerals in the lithosphere leaving huge gaping holes in the earth.
• The mine tailings are piled up in large mounds on the surface of the earth.
• Mining waste when washed into the water ways pollutes the hydrosphere.
• Mining causes air pollution to the atmosphere in several ways.
• The mine might also release poisonous gases that were trapped below the surface.
• Mining affects the biosphere by affecting the other three spheres in an indirect way.

Question 11.
Human beings consume a lot of medicines like anti-biotics to cure sickness. How do you think does it affect the lithosphere, hydrosphere and biosphere? (Text Book Page No. 14)
Answer:

• More than 10,000 tonnes of anti biotics are consumed in Europe each year.
• 30%-60% of them passthrough animals and humans unchanged and reach the ocean.
• These antibiotics can affect the marine ecosystems over a long period, with detrimental effects on natural marine communities of bacteria.
• The presence of antibiotics in the marine environment is worrying as it can reach to humans through the consumption of sea food and fish.
• The marine sediments affected by the antibiotics metabolise both nitrogen and carbon which are linked to both eutrophication and climate problems.

Question 12.
What are the dangers of living on the flood plains? (Text Book Page No. 23)
Answer:

• Flood plains are flood prone areas.
• Massive damage can occur during floods in flood plains.
• Homes, automobiles, buildings, historical monuments, graves, sewer systems, bridges and countless other infrastructure can be destroyed.
• Road ways often suffer. High flooding often claims the lives of drowning victims.
• In flood plains during floods there will be lack of clean drinking water which causes illness and epidemics to spread.
• Thus there are a lot of dangers of living on the flood plains.

Question 13.
Locate the Himalayas, Andes and Rockies mountains. Why were they formed in those locations? Suggest reasons. (Text Book Page No. 17)
Answer:

1) Himalayas
2) Rockies mountains
3) Andes mountains

Reasons:

1. Fold mountains are mountains formed from the folding of the earth’s crust.
2. The Himalayas, the Andes and the Rockies are fold mountains.
3. These fold mountains are formed when two plates move together.
4. The Himalayan mountains were formed by the process of Indian plate pushing the Eurasian plate.
5. The forces of plate tectonics are responsible for the formation of Andes.
6. The Nazce plate and a part of the Antarctica plate have been subducting beneath the South American plate.
7. The Rockey mountains took shape during an intense period of plate tectonic activity that resulted in much of the rugged landscape of the Western North America.
8. The Laramide Orogeny was responsible for raising the Rocky mountains.

Question 14.
You may have noticed that many of the ‘scientific’ terms use Greek words. Why do you think do they use Greek words? Discuss with your teacher. (Text Book Page No. 14)
Answer:
In his communication a scientist is mainly concerned with exact and logical expression of that which he wishes to pass on to another. His purpose is to inform as clearly as possible. Each of his words must have a precise meaning and one meaning only so that there is no risk of confusion or ambiguity. The meanings of many ordinary words of our language are not single and precise. The use of words which are ‘set apart’ from everyday life also enables the scientist to avoid evoking irrelevant and distorting associations.

In addition to precision of meaning and freedom from associations most scientific words by their form and structure they reveal something of their meanings. Many scientific words are built from simpler word-elements usually of Greek origin. Some words are self-explanatory if the Greek roots are known.

Scientific language to be efficient must be universally intelligible. The classical language Greek is so fundamental to the civilised world. The words constructed from this language can easily be learnt to be translated.

So scientific terms use Greek words.

Question 14.
Are all rocks on the earth formed in the mid-ocean ridges? (Text Book Page No. 17)
Answer:
No. All the rocks on the earth are not formed in the mid-ocean ridges. Only ocean rocks or crust are formed of the mid-ocean ridges. These are formed by lava rising up from the mantle. The eruptions on the ridges create new ocean floor made of basalt rocks, which then spreads laterally from the ridge. The first order landforms such as oceans and continents are formed at the time when the hot earth was cooling. While the earth’s interior continued to cool, it contracted and the outer crust wrinkled forming ridges i.e., mountains and basins i.e., oceans. The second order landforms such as plains, plateaus and mountains are formed as a result of the internal processes of the earth. The third order landforms such as carved mountains, valleys, deltas, sand dunes are formed as a result of the shaping of the land forms by wind, water.

Question 15.
Why do you think we don’t feel any of these mighty changes taking place on the earth? Is it because they don’t affect us? Do you think these changes affect us at all? (Text Book Page No. 17)
Answer:

• Two kinds of changes take place in the Lithosphere – first the very slow movements leading to the formation of the crust, movement of the continental plates and their eventual return to the mantle.
• Since these geophysical changes occur over thousands and even millions of years we don’t feel any of these changes.
• Secondly the sudden and dramatic eruption of volcanoes and earthquakes.
• The sudden movements can be destructive and cause much damage. At the same time they also lead to changes in landforms.

Question 16.
Compare the action of the river in the mountains and in the plains. In what ways are they similar and different?
Answer:
Similarities :

1. They carry something when they flow across the two landforms.
2. They have streams in both the areas.
3. They change the surface of the earth.

Differences

In the mountains	In the plains
1. Rivers originate in mountains.	1. Rivers run and flow across the plains.
2. They flow very fast.	2. They flow slowly.
3. They carry the rocks.	3. They deposit the sediments here.
4. They form gorges and canyons here.	4. They form deltas here.

From the mountains to delta, a river does not just flow – it changes the surface of the earth.

It cuts rocks, moves boulders, and deposits sediments.
It constantly attempts to carve away all the mountains in its path.

The goal of the river is to create a wide, flat valley which it can flow smoothly towards the ocean.

That is the relation between the mountains and plains.

Question 17.
Why is a flood plain more suited to human habitation compared to mountains? (Text Book Page No. 23)
Answer:
Disadvantages of mountains :

1. High elevation on mountains produces colder climates than at sea level.
2. These colder climates strongly affect the human habitation.
3. Climate of mountains to be used less for agriculture.
4. Abundant water supply.
5. Fertile land – rich for farming and agriculture.
6. Easy to develop than hilly regions.
7. Flood water can be stored temporarily.
8. Many civilizations are flourished on the banks of the rivers.
   These are all more suited to human habitation compared to mountains.

Question 18.
Recall the life of people living in the hills or flood plains that you may have read of. (Text Book Page No. 23)
Answer:
Bison hills are spread in both Bhadradri Kothagudem and W. Godavari districts along either banks of the river Godavari. Many tribal communities live in the hill tracts of this region with their own special life.

These tribals live in small habitations – about 5 to 10 hutments in one place. The habitations are far from each other.

Konda Reddys grow crops in a distinct way called Podu. When rains arrive in June they dibble seeds with the help of digging seeds.

Except for a few months during and after harvest, Konda Reddy women and children are engaged in collection of edible forest produce for subsistence.

There are no rivers or wells in this area. They fetch water from natural springs.

These hill tribes are very few in number but they follow a pattern of life which is very ancient.

Question 5.
Why government in 1990s allowed private industries in many areas which were earlier restricted only to government?
Answer:

• Indian industry as a result of government’s control was not modernizing fast and was producing goods at high cost and not making technological improvement.
• Government used to allocate a specifc amount every year to operate these industries.
• It was expected that these industries become independent, generate revenue for the government.
• But these government run factories continually require government assistance.
• Their functioning was much below that was expected.
• So, in the 1990s a new industrial policy was announced. Many activities which were earlier restricted only for the government are now allowed for the private industries.

Question 6.
What is the impact of industrial development on employment generation?
Answer:

• An important goal of industrial policies in India was to generate employment opportunities in industrial activities.
• Raising the proportion of people employed in factories is also generally seen as an important indicator of economic development of a country.

• These units employ nearly about one-fifth of India’s 460 million workers.
• Number of employees generated in industrial section has increased from 11% in 1972-73 to 22 % in 2009-10.
• But large industries began to replace workers with technology. More and more automation has taken place.
• This has led to almost zero additional employment in large factrories.

Question 7.
What is the impact of industrial development on revenue?
Answer:

• When goods made in factories and exported to other countries, we get revenue.
• A few decades before, three-fourths of income from goods exported from manufacturing industries alone.
• Even today, nearly two-third of goods exports is contributed by industries and particularly small industries.
• Factory goods exported range from gems, jewellery, chemicals, cars, machinery, cashewnuts, etc.
• The money or foreign exchange earned in this process enable us to import from other countries a large number of goods that we want from other countries.

Question 8.

B) Democracy can’t reduce inequality of incomes between different citizens.
Answer:
We do not agree with the statement. Democracy can’t reduce inequality of incomes between different citizens. But democracy can reduce the economic inequality by providing equal distribution of wealth and equal opportunities to all.

C) Government in poor countries should spend less on poverty reduction, health, education, and spend more on industries and infrastructure.
Answer:
We do not agree with this statement. Poverty is one of the social challenges which democracy has to accommodate, so poor countries should spend more to check poverty.

Besides food, clothing, health and education are the basic needs of the people and it is the duty of the government to provide these facilities to the people.

D) In democracy, all citizens have one vote, which means that there is absence of any domination and conflict.
Answer:
Yes, we do agree with the statement. Democracy stands for political equality and guarantees Universal Adult Franschise. Universal Adult Franchise gives right to vote to every adult citizen of the country. Hence there is no chance of political domination and conflict.

Question 4.
In the context of assessing democracy, which among the following is odd one out? Democracies need to ensure :
A) free and fair elections
B) dignity of the individual
C) majority rule
D) equal treatment before law
Answer:
(C) Reason : Majority rule is odd one out because democracy ensures people’s rule based on popular consensus.

Question 5.
Studies on political and social inequalities in democracy show that:
A) democracy and development go together.
B) inequalities exist in democracies.
C) inequalities do not exist under dictatorship.
D) dictatorship is better than democracy.
Answer:
(B) Inequalities exist in democracies

Question 6.
Here is some information about six countries. Based on this information, how would you classify each of these countries? Write ‘democratic’, ‘undemocratic’ or ‘not sure’ against each of these.
i) Country A : People who do not accept the country’s official religion do not have a right to vote
ii) Country B : The same party has been winning elections for the last twenty years
iii) Country C : Ruling party has lost in the last elections
iv) Country D : The parliament cannot pass a law about the army without the consent of the Chief of Army
v) Country E : The parliament cannot pass a law reducing the powers of the judiciary
vi) Country F : All the major economic decisions about the country are taken by officials of the central bank which the ministers cannot change,
Answer:

i) Undemocratic
ii) Not sure (More details are needed)
iii) Democratic
iv) Undemocratic
v) Democratic
vi) Undemocratic

Question 7.
Each of these statements contains a democratic and an undemocratic element. Write out the two separately for each statement.
A) A minister said that some laws have to be passed by the parliament in order to confirm to the regulations decided by the World Trade Organisation.
Answer:
Passing laws by the parliament is democratic whereas passing it in confirmity to the regulations decided by WTO is undemocratic.

B) The Election Commission ordered re-polling in a constituency where large scale rigging was reported.
Answer:
To order repoll in a constituency by the Election Commission is democratic whereas rigging is undemocratic.

C) Women’s representation in the parliament has never reached 10 per cent. This led women’s organisations to demand one-third seats for women.
Answer:
Demand by women’s organisation to reserve 1/3 seats for women is democratic whereas less 10% women’s representation in the parliament is undemocratic.

Question 8.
Write a response to the following arguments against democracy :
A) Army is the most disciplined and corruption-free organisation in the country. Therefore army should rule the country.
Answer:
Army rule is always undemocratic. Under this system, people do not enjoy freedom of speech and expression and are not allowed to criticise the government. Military rule is another name for dictatorship. Moreover, many army men are not disciplined and are corrupt.

B) Rule of the majority means the rule of ignorant people. What we need is the rule of the wise, even if they are in small numbers.
Answer:
Rule of majority is democratic as it represents the views of all sections of the people.

C) If we want religious leaders to guide us in spiritual matters, why not invite them to guide us in politics as well. The country should be ruled by religious leaders.
Answer:
Rule by religious leaders is not democractic. It arouses communal feeling among the people which sometimes lead to communal riots. Besides many religious leaders do not have any experience of administration.

Question 9.
Locate the following countries in the world map.
1. Sri Lanka
2. Belgium
3. Russia
4. America (USA)
Answer:

Question 10.
Read the first two paragraphs under the subheading ‘Dignity and freedom of the citizens’ and answer the following question.

Democracy stands much superior to any other form of government in promoting dignity and freedom of the individual. Every individual wants to receive respect from fellow beings. Often conflicts arise among individuals because some feel that they are not treated with due respect. The passion for respect and freedom are the basis of democracy. Democracies throughout the world have recognised this, at least in principle. This has been achieved in various degrees in various democracies. For societies which have been built for long on the basis of subordination and domination, it is not a simple matter to recognise that all individuals are equal.

Take the case of dignity of women. Most societies across the world were historically male dominated societies. Long struggles by women have created some sensitivity today that respect to and equal treatment of women are necessary ingredients of a democratic society. That does not mean that women are actually always treated with respect. But once the principle is recognised, it becomes easier for women to wage a struggle against what is now unacceptable legally and morally. In a non-democratic set up, this unacceptability would not have legal basis because the principle of individual freedom . and dignity would not have the legal and moral force there. The same is true of caste inequalities. Democracy in India has strengthened the claims of the disadvantaged and discriminated castes for equal status and equal opportunity. There are instances still of caste-based inequalities and atrocities, but these lack the moral and legal foundations. Perhaps it is this recognition that makes ordinary citizens value their democratic rights.

Write about the dignity and freedom of the citizens in a democratic country in your own words.
Answer:

• In a democratic country people have freedom to choose their representatives on the basis of universal adult franchise.
• Most societies across the world are male dominated. Equal treatment of women became the necessary requirement of a democratic society. Thus their status in democratic countries improved.
• In a non-democratic set up, there is no legal basis for freedom and dignity of individuals.
• Democracy in India has strengthened the claims of the disadvantaged and discriminated castes for equal status and equal opportunity.
• Democracy transforms people from the status of subjects under a king or a dictator to the status of citizens with rights and duties.
• Many fundamental rights are granted to citizens in a democratic country. One such right is to travel anywhere, freedom to any profession, to choose any religion, etc.

Question 11.

1. A democracy is the best form of government.
2. Democracy promotes equality.
3. It promotes dignity and freedom of the individual.

9th Class Social Studies 20th Lesson Democracy: An Evolving Idea InText Questions and Answers

Question 1.
Discuss the solutions given in both the countries to accomodate social, religious, and linguistics diversity in them. (Text Book Page No. 254)
Answer:
Both are democracies. Yet, they dealt with the question of power sharing differently. In Belgium, the leaders have realised that the unity of the country is possible only by respecting the feelings and interests of different communities and regions. Such a realisation resulted in mutually acceptable arrangements for sharing power. Sri Lanka shows us a contrasting example. It shows us that if a majority community wants to force its dominance over others and refuses to share power, it can undermine the unity of the country and force the country back several hundred years with internal conflicts and civil wars.

Question 2.
How will this chess board change? (Text Book Page No. 247)

Answer:
If the inequalities are vanished, the chess board will change.

Question 3.
If a party is repeatedly voted to power, does it mean that people really want it to come to power, or that there is no alternative or that people are not allowed to vote for any alternative? Answer on the basis of the following three case studies: (Text Book Page No. 249)
a. Since its independence in 1930, Mexico holds elections after every six years to elect its President. The country has never been under a military or dictator’s rule.But, until 2000, every election was won by a party called PRI (Institutional Revolutionary Party). Opposition parties did contest elections, but never managed to win. The PRI was known to use many unfair means to win elections. Teachers of government schools used to force parents to vote for the PRI.

b. Zimbabwe attained independence from White minority rule in 1980. Since then, the country has been ruled by ZANU-PF, the party that led the freedom struggle.Its leader, Robert Mugabe, has been ruling the country since independence. Elections have been held regularly and always won by ZANU-PF. President Mugabe is popular but also uses unfair practices in elections. His government has changed the Constitution several times to increase the powers of the President and make him less accountable. Opposition party workers are harassed and their meetings disrupted. There is a law that limits the right to criticise the President. Television and radio are controlled by the government and give only the ruling party’s version.

c. In China, elections are regularly held after every five years for electing the country’s parliament, called Quanguo Renmin Daibiao Oahui (National People’s Congress). The National People’s Congress has the power to appoint the President of the country. It has nearly 3,000 members elected from all over China. Some members are elected by the army. Before contesting elections, a candidate needs the approval of the Chinese Communist Party. Only those who are members of the Chinese Communist Party or eight smaller parties allied to it were allowed to contest elections held in 2002-03. The government is always formed by the Communist Party.
Answer:

1. Democracy requires free and fair elections.
2. People should have choice to vote.
3. People should not be forced by the government.
4. Electoral rolls should maintained in a right way.

In these 3 cases, these conditions are not fulfilled. So we can say that the elections are conducted in an undemocratic way.

Question 4.
Let us take the example of an election in India. Of all the residents in a region, let us assume that 1000 have right to vote. In any typical election about 60% people go to cast their votes. Thus, we have 600 people voting in an election. Let us assume that there are ten candidates in the election and of these the winning candidate gets about 250 votes, the second candidate gets 200 votes and the other candidates between them get about 150 votes. We declare the one with 250 votes the winner. Does he or she really represent the views and interests of the residents of the locality? Actually, he or she only represents one fourth of the voters. Is this a fair democratic arrangement ? Can there be better ways of representing the people in decision making bodies? (Text Book Page No. 250)
Answer:
He or she really represents the views and interests of the majority people of the locality. This may not be a fair democratic arrangement.

This controversial new look at democracy in a multicultural society considers the ideas of political inclusion and exclusion and recommends ways to engage in democratic politics in a more inclusive way. Processes of debate and decision making often marginalize individuals and groups because the norms of political discussion are biased against some forces of expression. Inclusion and democracy broadens our understanding of democratic communication by reflecting on the positive political function. It reconstructs concepts of civil society and public sphere.

Question 5.
Do the millions of poor people really have any control over the functioning of the elected functionaries? (Text Book Page No. 246)
Answer:
In a democracy, every citizen has certain basic rights that anyone cannot take away from them. I think people are using this during the time of elections.

Question 6.
Does democracy mean rule by people or merely rule by elected persons? (Text Book Page No. 246)
Answer:
Literally, democracy means rule by people only. But in practice, it is rule by elected persons.

Question 7.
How can people really participate in government on a day to day basis? (Text Book Page No. 246)
Answer:
This is possible when all policies and laws are made after extensive public discussions, in which people participate and openly state their needs and views. It also requires that people be involved in effective implementation of the policies and laws – by forming independent citizens committees.

Question 8.
Why do people not want to participate in governance? Is it because of poor knowledge or lack of interest or a feeling that they don’t have a real say in things? (Text Book Page No. 247)
Answer:
The people remain apathetic and they lose their interest in politics. Fore.g. : whoever may be the elected representative, he tries to save his position and wealth, etc.
So they do not want to participate in governance.

Question 9.
Why do you think does such high level of inequality persist even where the countries are democratic and government works in the interest of all people? (Text Book Page No. 248)
Answer:
In many countries like the USA, most of the media are owned by very rich corporate houses or media barons. They effectively manipulate and influence public opinion by what they high light and what they black out. The rich and powerful also have immediate access to members of the legislature and the ministers, and are in a position to influence their policies and programmes.

On the other hand, the poor and illiterate people have no such access to the government circles. Thus the government of many of these countries follow policies which seem to be contradictory to the interests of the poor and in favour of the rich.

So the high level of inequality persists even where the countries are democratic and government works in the interest of all people.

Question 10.
Even today, most countries do not give voting powers to people who have migrated from other countries. Actually, millions of people across the world live without these democratic rights simply because the countries they live in treat them as illegal immigrants. This is the plight of South American immigrants in the US or Turkish immigrants in France or Germany. Such immigrants and refugees are found all over the world including India. Should they not be part of democratic governance? (Text Book Page No. 247)
Think of some reasons for your answer.
Answer:
Democracy is based on the fundamental principle of political equality and inclusiveness. In a democracy, each adult citizen must have one vote and each vote must have one value. So they should also be a part of democratic governance.

Question 11.
Many governments give people the civil liberties. But they keep a careful watch on the activities of the citizens by tapping their telephones and letters, spying on them etc. Do you think this is justified? (Text Book Page No. 248)
Answer:
Today the conditions in the world are so. All the countries are in the shadow of terrorism. So the governments are supposed to do like that. But the government should not disclose the secrecy of the individuals. Then only I think this is justified.

Question 4.
Why is it difficult to study the formation of the earth and its structure?
Answer:
Earth formed around 4.54 billion years ago by accretion from the solar nebula. Nearly all branches of natural science have contributed to the understanding of the main events of the earth’s past. The age of the earth is approximately one-third of the age of the universe. Biological and geographical change has been constantly occurring on our planet since the time of its formation. The process of plate tectonics has played a major role in the shaping of earth’s oceans and continents as well as the life on it.

It took us years of scientific investigation and analysis of data to form an understanding of the interiors of the earth. The main reason for this is that even the deepest mines we have dug do not go beyond a few kilometers under the surface while the radius or the distance to the centre of the earth is over 6000 kilometers.

Thus it is very difficult to study the formation of the earth and its structure.

Question 5.
Read the paragraph under the heading of “Internal structure of the earth” and answer the question.

Internal Structure of the Earth : Let us look at the internal structure of the Earth we live on. We can see the continuity from the early days of the formation of the earth as we try to look deep inside the Earth! It took us years of scientific investigation and analysis of data to form an understanding of the interior of the Earth. The main reason for this is that even the deepest mines we have dug do not go beyond a few kilometres under the surface while the radius or the distance to the centre of the earth is over 6000 kilometres!

How can you say the earth is still very active?
Answer:

• The matter deep inside the mantle shoots up through volcanoes and fissures on ocean floors.
• In many regions on the earth part of the earth’s crust enters into the mantle and once again becomes molten.
• The crust is still being changed by earthquakes, volcanoes, subduction of land and rise of mountains due to the processes happening deep down the earth.
• This constant process of formation and destruction of the earth’s crust explains the fact that the earth is still very active.

Question 6.
What is a grid and how does it help us?
(OR)
Write any two uses of the ‘Grid system’ located on the globe.
Answer:
Grid : A grid is a sqaure or a rectangle that is formed between when two latitudes and longitudes out across each other. In other words the network of latitudes and longitudes drawn on the globe is called a ‘grid’.

Uses of grid:
1. Network of latitudes and longitudes is called a Grid.

2. Uses of a grid :
a) To locate a place
b) How hot or cold it would be there,
c) To know the time.

Question 7.
Differentiate between
a) Local and Standard time
b) Equator and Prime meridian.
Answer:
a) Difference between Local and Standard time :

Local Time	Standard Time
1) The time of a place when the mid day sun is over head is called local time.	1) The local time of the standard meridian of a country is called a standard time.
2) It changes from place to place.	2) It remains same for that particular country.
3) The place on the same longitude has the same local time.	3) The place on the same longitude has the different standard time.

Example: If the 1ST is 12.00 noon, the local of Mumbai is 39 minutes – 1ST = 11.21 minutes a.m.
Since Mumbai is on 72°82′ east longitudes, it is 9°45′ behind the 82°30′. Thus the local time of Mumbai is 9.45 x 4 = 38 minutes.

b) Differences between Equator and Prime meridian :

Equator	Prime meridian
1) Equator is 0° latitude.	1) Prime meridian is 0° longitude.
2) Equator divides the earth into parts, i.e. Northern hemisphere and Southern hemisphere.	2) The Prime meridian divides the earth into two equal parts i.e., Eastern hemisphere and the Western hemisphere.
3) Equator is a circle.	3) Prime meridian is a semi-circle.
4) It is an imaginary line that runs east and west around the exact middle of the globe. (A horizontal line)	4) It is an imaginary line running from pole to pole and passing through Greenwich, England. (A vertical line)

Question 8.
If every state follows its local time then what problems will rise?

If every state follows4ts local time, a lot of serious problems would rise. Some of them are being discussed hereunder.

1. At the time of national calamities and disasters, it is very difficult for the national government to make necessary emergency announcement.
2. At the time of wars and national emergency, it is very difficult for the national government to alert all the defensive forces stationed in all the state capitals and the naval forces of all the coastal states.
3. It is very difficult for Televisions and Radios to follow a single schedule to broadcast their programmes.
4. Railways faces a difficult problem in preparing a timetable for its trains that travel through many states.

Question 2.
We cannot hope to travel to the mantle to study it. But we can study substances from the mantle. Can you tell what these substances would be and how we can get them? (Text Book Page No. 5)
Answer:
1) The thickness of the mantle is 100 – 2900 kms. So we cannot hope to travel to the mantle to study it.
2) Interestingly the matter from the deep inside the mantle shoots up through volcanoes and fissures on ocean floors and cools down to form the earth’s crust.
3) Thus by studying the lava or magma or the substances brought up through the fissures, we can study the substances from the mantle.

Question 3.
When it is 12 noon in Greenwich (0°), what is the local time at: (Text Book Page No. 12)
a) Mumbai (73° E)
b) Chicago (87°30′ W)
c) Sydney (151° E)
Answer:
a) Mumbai (73° E) :
Local time at Mumbai is : 73 × 4 = 292 minutes, i.e. 4 hours 52 minutes. That means the local time at Mumbai is 4 hours 52 minutes after 12 noon i.e., 12.00 + 4.52 = 4.52 p.m.

b) Chicago (87°30′ W):
Local time at Chicago is : 87°30′ × 4 = 350 minutes, i.e. 6 hours 50 minutes. That means the local time at Chicago is 6 hours 50 minutes less than 12.00 noon at Greenwich. i.e. 12.00 – 6.50 = 5.10 a.m.

c) Sydney (151° E): Local time at Sydney is 151° × 4 = 604 minutes, i.e. 10 hours 4 minutes before Greenwich time.
That means the local time at Sydney is 12.00 + 10.04 = 10.04 p.m

Question 5.
Swathi works for a call centre in Hyderabad. Her clients are in the U.S.A. She answers clients’ questions about the computer problems. She always works during the night. Why is this? Use geography to find out! (Text Book Page No. 12)
Answer:
Indian Standard Time is the time observed in India. Its time offset is UTC + 5.30.
United Standard Time is the Central Standard Time. Its time is GMT – 6.00. Thus there is a difference of 11½ hours between Indian Standard Time and American Standard Time. Thus if it is day time in America, in India it is night time. If an American client asks Swathi a question at 11 am in America, Swathi has to answer the same at 10.30 p.m the same day. Thus Swathi should always work at night to answer his clients from the U.S.A.

Question 9.
Initially people thought that the earth was in the centre of the universe and human beings the most important creation. What difference does it make to us to know that we are a small insignificant speck in this vast universe? (Text Book Page No. 2)
Answer:
The earth we live on seems big and very important to us. But in the universe as a whole, it is tiny and very insignificant speck of rock. To put things into perspective earth is just a small planet in the solar system, part of a family of bodies that circle round the sun. The sun is just one of billions of stars that makes up our galaxy, and this galaxy is just one of billions that make up a universe bigger than most of us can imagine.

Question 10.
Do you think the Earth was created suddenly or do you think it was formed by long drawn and complex processes? (Text Book Page No. 4)
Answer:
The Earth began to form around four and a half billion years ago. The earth has reached its present form through several phases but not created suddenly.

• It began as a ball of swirling dust and clouds and passed through a molten stage.
• The molten Earth was very hot and was constantly bombarded by massive rocks and other materials from the space. In this way the size of the earth grew.
• When the earth was so hot and in liquid form the heavier particles went to the bottom and formed core and the mantle.
• The lighter particles cooled at the top and formed the crust.
• While the earth’s interior was cooling, it contracted and outer crust wrinkled forming ridges (i.e., mountains) and basins (i.e., oceans)
• It took a long time for the air we breathe to develop.
  Thus we can say that the earth was not created suddenly but formed through several phases.

Question 11.
Some people believe that our being on this earth is the result of a series of fortuitous accidents – it is quite possible that there may not have been any life on the earth. Do you agree? Give your reasons. (Text Book Page No 4)
Answer:
Yes, the earth’s creatures have evolved through a series of contingent and fortuitous events.
1. Our earth is just the right distance from the sun to have a stable orbit. Our orbit keeps us from getting too hot or too cold to survive. Any closer we’d burn up, any farther away we’d freeze to death.

2. Our earth is perfect in both size and mass. Mass is critically important to the formation of an atmosphere. If the earth’s mass were less dense, an atmosphere could not have formed and remained. If it were more dense, the atmosphere would have been uninhabitable.

3. Our earth has just the right mix of the 27 elements needed for life, including carbon, oxygen, nitrogen, phosphorous, potassium, iron, sodium, and copper.

4. Our earth has just right amount of water in the proper ratios of liquid, solid, and gas.

A little more and the continents would probably be totally overrun with water and literally, drown. Any less and the temperature of the earth would probably be too hot making life unbearable here.

Thus we can say that our being on this earth is the result of fortuitous accidents.

Question 1.
Map 1: Democratic Governments in 1900 – 1950

Map 2 : Democratic Governments in 2011

a) On the basis of these maps, identify up to three countries (in some cases you won’t find three countries) that were democratic in these continents for the given years and make a table as given.

Answer:

b) identify some African countries with democracy in 2011.
Answer:
Egypt, Libya, Tunisia are countries which got independence in and around 2011.

c) Make a list of big countries that were not democratic in 2011.
Answer:
1) Asian countries :
China, Kazakhstan, Turkmenistan, Saudi Arabia, etc.

2) African countries :
Algeria, Ethiopia, Chad, Zaire, Morocco, Mauritania, Angola, etc.

The above countries were not democratic in 2011.

Question 2.
Read the maps again and think about the following points.
a) Based on the maps, can we say that the Twentieth century was a significant era for the spread of democracy?
Answer:

1. At the beginning of the 20th century only few countries of Europe and America were independent, e.g.: Spain, France, England, Norway, Argentina, Chile, Bolivia and Peru, the USA, Canada, Alasca.
2. After World War II almost all countries fought against colonial powers and got independence.
3. Though there are still some non-democratic countries, we can call 20th century as an era of democracy.

b) During the early 20 century, democracy was mostly in the continents like Europe and Americas. While in certain continents like Africa and Asia there were almost no democratic countries.

c) Even today there are certain areas that have not established democratic governments such as Saudi Arabia and Ethiopia.

Question 3.
Most countries often claim themselves to be democratic by conducting elections. How did this occur in the context of Myanmar and Libya?
Answer:

1. Both the countries Myanmar and Libya claim themselves as independent and democratic.
2. But in practical view, they are not democratic countries.
3. Unlike democratic countries –
   a) They did not allow multi-party elections and one party usually ruled for several years.
   b) Even they did not allow free elections.
   c) Sometimes they did not allow the elected representatives to form governments.
   Ex : NLD, led by Suu Kyi got 80% seats, was not allowed to form government.
   d) They did not allow freedom of expression or freedom to form organizations, or freedom to protest against government.

Both the countries did not have any conditions for a democracy to flourish. Hence they cannot claim themselves to be democratic by conducting elections.

Question 4.
Why do you think the rulers try to control the media? Do you know how is media controlled in your area?
Answer:

• Mass Media is powerful weapon which can make or break any governments.
• Restrictions on media helps them to remain in power.
• Hence the rulers always try to control the media.
• So many times in India too government censors certain news. This generally happens without the notice of common man.

Question 5.
Write an imaginary dialogue between a person from Libya and Myanmar comparing the events and struggle for democracy in their respective countries.
Answer:
Person from Libya : Hai, I am xxxx, as I have already told you the monarchy is over thrown in our country.
Person from Myanmar : Yes, I came to know about that who is ruling your country now.
Libya : Gaddafi has taken control of our country. What about your country.
Myanmar : In 1962, the government was overthrown and ‘Ne Win’ military rule is going on.
Libya : First of all we thought he could rule us. He laid foundation for development. What is your country’s position?
Myanmar : Under military rule, our country did not make any progress.
Libya : UNO is supporting our people’s to demands.
Myanmar : Other countries are also showing sympathy us.
Libya : We protested against.
Myanmar : Suu Kyi is in house arrest she played good role.
Libya : Gaddafi is overthrown in 2012. O.K. Bye.
Myanmar : We got new government in 2012. Bye.

Question 6.
How do literacy and mass education help for the functioning of democracy?
(OR)
How do the literacy help for the effective functioning of democracy?
Answer:

• Literacy and education play an important role in the development of individual and society.

What is a new kind of democracy?
Answer:

1. The poorest and the most vulnerable people will have a voice.
2. The poorest will be able to influence the policies.
3. The new kind of democracy will ensure justice and peace for ail.

Question 10.
Read the newspapers and note down any news regarding struggle for democracy in Libya or Egypt or any other country. Prepare a file of such news clippings and display in the classroom.
Answer:
Struggle for democracy in Libya :
A few months ago the National Transitional Council (NTC), which has governed Libya since the first few weeks of the revolt in 2011, announced that the assembly would not draft the constitution itself but instead appoint a 60-member committee to draft it. The members of this committee were supposed to be chosen from outside the assembly and represent the country’s three geographic regions of Libya – Tripolitania, Cyrenaica, and Fezzan — in equal numbers. Yet, a few weeks ago, the NTC changed policy again at the last moment, declaring that the members of the constitutional committee would not be appointed by the assembly but directly elected by the people, though it’s not clear when. Confused? So are Libyans.

There are rumors in Libya that most members of the NTC are not happy about the idea of dissolving the institution and going back home. It’s just a rumor, but the group’s decision to revoke constitution-writing powers from the new assembly is making people suspicious, and that’s the point. The NTC likely fears too much power going to Islamists, who are notoriously less friendly toward the NTC than are other groups. We can’t know the NTC’s motivations for sure, but their recent moves diminished the power of the new assembly, which they may have feared would be dominated by Islamists, who swept national elections in neighboring Tunisia and Egypt. A more democratic Libya would re¬ject the NTC’s odd rule-changing and reinstate the elected assembly’s power to write the constitution. After all, this is what Libyans voted for. So should the same Western powers that supported the Libyan revolt.

Libya has come a long way since Gaddafi’s fall, but it still hasn’t been able to solve two major security problems: the armed militias that still roam the country and the state’s deteriorating control of its national borders. Fortunately, this is where new assembly can step in, finding agreement among the various parties and militias and forming a govern-ment, one that is as inclusive as possible, to administer and rebuild Libya. The interna-tional community can help, including by training and equipping the police and security forces, both of which were devastated by the recent conflict.

A successful election is just the start of dealing with one of Libya’s most important challenges right now: national unity. Regional and local claims and jockeying for power threaten to undermine the legitimacy of and support for the national government. A few thousand inhabitants of the eastern provinces care calling for a federalist state, if not of outward secession. While this is definitely a minority position, it is a very dangerous one because it could easily, at the administration’s first real difficulty, split the government and the people, thus slowing or even reversing Libya’s progress toward stability. Most Libyans, as well as the interested Western nations, are rightly happy with Libya’s progress toward becoming a stable, unified, democratic state. But if they want that progress to continue, they’ll all have to work together.

9th Class Social Studies 19th Lesson Expansion of Democracy InText Questions and Answers

Question 1.
What kind of problems do you think these pose for establishing democratic government? (Text Book Page No. 235)
Answer:

• Bringing democratic participation of all the people under conditions of tribalism, normalism, illiteracy, and restrictions on women was difficult.

• There was no freedom of press and no one could start any trade union or other associations.
• The civic amenities were deplorable.
  Hence rebellions rose against the government of Gaddafi.

Question 3.
Even though the Gaddafi government claimed to be a democratic government, what aspects of democracy were absent? What aspects of democratic government were present in it? (Text Book Page No. 237)
Answer:
Aspects of democracy absent in the government of Gaddafi:

1. Democratic bodies had to implement the decisions of non-elected leaders.
2. Freedom of press, freedom to form trade unions and associations were prohibited.
3. No political parties were allowed to function in Libya.
4. This led to concentration of power and wealth in the hands of few.

Aspects of democracy present in the government of Gaddafi :

3. Oil profits were distributed to all the citizens.
4. Subsidised housing schemes were introduced.
5. Women were given with equal opportunities and status in the society.

Question 4.
Why are civil liberties important for democracy? Explain in the context of Libyan experience. (Text Book Page No. 237)
Answer:

• “Liberty” is one of the aspects of democracy.

• These “liberties” were missing in Libya.
• Liberty of expression was brutally crushed.
• The RCC was also very intolerant of criticism and opposition.
• People were not at liberty to express their discontent.
  Thus lack of civil liberties led to the downfall of the government of Gaddafi in Libya.

Question 5.
Why do you think democracy was not able to establish itself in Burma after its independence? (Text Book Page No. 240)
Answer:

• Burma became independent just 5 months after Indian independence.

Why is it important to know the latitude and longitude of a place on map? How can it be useful? (SA-II : 2018 – 19)
Answer:
It is very important to know about latitudes and longitudes of a place by the following reasons.

• The particular location of a place on the earth can only be traced precisely with the help of latitude and longitude of that place.
• Latitude also help us in understanding the pattern of wind circulation on the global surface.
• Longitudes are useful to us to define the east-west position of a location on the planet.
• Longitudes are useful to us to know the time of the place.

9th Class Social 1st Lesson Our Earth 4 Marks Important Questions and Answers

Question 1.
What is the difference between local time and standard time ? If every state follows its local time then what problems will rise in India? (SA-III : 2015 – 16)
Answer:
Difference between Local and Standard time:

Local Time	Standard Time
1) The time of a place when the mid day sun is over head is called local time.	1) The local time of the standard meridian of a country is called a standard time.
2) It changes from place to place.	2) It remains same for that particular country.
3) The place on the same longitude has the same local time.	3) The place on the same longitude has the different standard time.

Example:
If the IST is 12.00 noon, the local of Mumbai is 39 minutes – IST = 11.21 minutes a.m. Since Mumbai is on 72°82′ east longitudes, it is 9°45′ behind the 82°30′. Thus the local time of Mumbai is 9.45 x 4 = 38 minutes.

If every state follows its local time, a lot of serious problems would rise. Some of them are being discussed hereunder.

• At the time of national calamities and disasters, it is very difficult for the national government to make necessary emergency announcement.
• At the time of wars and national emergency it is very difficult for the national government to alert all the defensive forces stationed in all the state capitals and the naval forces of all the coastal states.
• It is very difficult for Televisions and Radios to follow a single schedule to broadcast their programmes.
• Railways faces a difficult problem in preparing a timetable for its trains that travel through many states.

Question 2.
Describe the internal structure of the earth. (SA-III : 2016 – 17) (SA-I : 2018 – 19)
Answer:
The earth is made up of three main layers.
A) Crust:

1. The outer part of the earth on which we live is called the crust.
2. While the earth was boiling in a molten form the lighter particles cooled at the top and formed the layer of crust.
3. The curst mostly consists of various kinds of rocks.
4. This layer goes up to a depth of 30 to 100 kms.

B) Mantle:

1. While the earth was boiling in a molten form the less heavier particles settled in the middle and formed the mantle.
2. The upper part of the mantle is a pliable layer over which the crust floats.
3. This layer consists mainly of chemicals called silicates.
4. It exists at the depths from 100 kms to 2900 kms.

C) Core:

1. While the earth was boiling in a molten form the heaviest substances formed core.
2. It is composed of dense and heavy substances like Iron and Nickel.
3. It exists at the depths from 2,900 kms to 6,376 kms.
4. It can be divided into two sub-layers.

a) Outer core :
This layer is composed of liquid metallic material like nickel and iron. It is 2,900 – 5,100 kms in thickness.

b) Inner core :
The solid inner core is made up of iron compounds and heavy substances like gold. It is 5,100 – 6,376 kms in thickness.

9th Class Social 1st Lesson Our Earth Important Questions and Answers

Question 1.
How can you say the man himself is responsible for environmental crises?
Answer:

• More than any other animal human beings have been trying to make the earth a better place to live in.
• Trying to change ourselves and our surroundings we have entered into conflict with other inhabitants of the earth.
• For long we’ve been exploiting the earth for its resources.
• The reckless exploitation of the earth resulted in environmental crises such as global warming and poisoning of our soils, water and air.
• Thus we can say man himself is responsible for environmental crises.

Question 2.
What were the initial ideas of people about the earth, the sun the moon and other astronomical bodies?
Answer:

• For thousands of years humans have been looking into the sky trying to understand objects that shine there.
• Initially, people thought that earth was firm and stationary and all others went round it.
• They also thought that the earth, the stars and the sun have been like this forever and will be like this forever without any change.

Question 3.
Write about the phases of evolution of facts, about the astronomical bodies their birth and growth.
Answer:

• Initially, people were of the view that the earth was firm and stationary and all the other bodies went round it.
• About five hundred years ago scientists concluded that the earth is not in the middle of everything.
• The earth actually moves round the sun and that the sun itself is also moving.
• The countless stars in the sky are actually so many suns.
• During the last hundred years or so people learnt the stars are born, they grow old and even die.
• Scientists even came to know that the stars are actually part of larger groups called galaxies.
• There are millions of galaxies in the universe.
• Now scientists are of the view that the universe itself started some 13.7 billion years ago with a Big Bang and it may end several billion years later.

Question 4.
How dkl the universe come into existence?
Answer:

1. The universe itself started some 13.7 billion years ago with a Big Bang.
2. From this Big Bang, several galaxies were formed.
3. Within these galaxies, stars were formed.
4. Planets were formed around stars and went around them.

However these astronomical changes take place over thousands and even millions of years.

Question 5.
Describe the process of evolution of the Earth.
(OR)
How did the earth come into existence and get its present form?
Answer:

• The earth began to form around four and a half billion years ago.
• It began as a ball of swirling dust and clouds and passed through a molten age.
• Gradually it grew in size.
• It was very hot and was in molten stage.
• The lighter particles cooled at the top and formed a layer of crust.
• Heavier particles formed the part of the molten core.
• As the earth’s interior cooled and contracted, the outer crust wrinkled, forming ridges and basins.
• The rain filled the basins and thus oceans formed.
• Slowly atmosphere developed and slowly life appeared on the earth.

Question 6.
How and when did the life appear on earth?
Answer:

• Different kinds of gases including water vapour formed the atmosphere on earth.
• Most of these gases were such that life as we know it today could not survive on it.
• Because it did not have oxygen necessary for life to survive.
• It took a long time for the air to develop.
• Then life appeared on oceans first.

It slowly evolved into diverse forms – plants, animals and human beings.

Question 7.
Are the shapes and positions of the continents fixed and permanent as they appear on the globe?
Answer:
The shapes and positions of the continents may seem fixed at the time scale of human experience. But on old earth continents have moved, collided, merged and then been torn apart again.

Mountains have risen and been razed to the ground, oceans have formed and dried up. Valleys have been carved and so during the course of earth’s eventful history. Alfred Wegener’s theory of Continental drift proves the same idea.

Thus the shapes and positions of the continents are not fixed and permanent.

Question 8.
Describe the theory of continental drift.
Answer:

• In 1912 Alfred Wegener propounded the theory of continental drift to describe the present arrangement of continents and ocean basins.
• He postulated a massive super continent Pangaea that existed 220 million years ago.
• Pangaea, the hypothetical continent, from which present continents originated by the drift from Mesozoic era to the present.
• Wegener hypothesized that the super continent of Pangaea broke up to from :
  a) Laurensia – consisting of present North America, Greenland and all of Eurasia north of Indian subcontinent and
  b) Gondwana land – consisting of present South America, Africa, Madagascar, Arabia, India, Malaysia, East Indies, Australia and Antarctica.
• These two blocks were separated by a long shallow inland sea called Tethys sea.
• It took millions of years for the continents to reach the present shapes and positions on the globe.
• Even today many of the continents are moving very slowly pushing each other.

Question 9.
What do you know about latitudes?
Answer:

• Latitudes are imaginary lines drawn around the earth.
• The word ‘latitude’ comes to us from the Latin word ‘iatitudo’ meaning width.
• Latitudes are also called parallels because they are parallel to each other.
• Latitudes are circles.
• Latitudes are expressed in degrees (°), minutes (‘) and seconds (“).
• Latitude values range from 0° t* 90° North (the North Pole) and 90° South (the South Pole).
• Thus there are 180° main latitudes (not counting the equator)
• Equator, the 0° latitude is the largest among all the latitudes.
• Latitudes are used together with the longitudes to locate a place on the earth.
• Latitudes are used to locate the climatic zones on the earth.

Question 10.
What do you know about longitudes?
Answer:

• Longitudes are imaginary lines connecting North and South’Poles.
• Longitudes are semi-circles.
• Longitudes are also called meridians because when the sun is overhead on a longitude at the time on that longitude it is noon (meridianus).
• There are 360 longitudes in total.
• The longitudes from 0° to 180° to the east are called eastern longitudes.
• The longitudes from 0° to 180° to the west are called western longitudes.
• 0° meridian is called the Prime meridian or Greenwich meridian.
• Longitudes are also expressed in degrees (°), minutes (‘) and seconds (“).

Question 11.
How are the time zones formed and why are they formed?
Answer:

• It takes 4 minutes for the sun’s position to move 1° of longitude.
• This means that the time is different for each degree of longitude.
• This can cause a lot of confusion.
• Therefore to end up this confusion the world is divided into 24 time zones.
• The width of each time zone is 15° of longitude.
• This means the difference between one time zone and the next is 1 hour.
• As you go from Greenwich meridian, you add time; as you go west of the Greenwich meridian you subtract time.

Question 12.
Why does every country have its own standard time?
Answer:

• The world is divided into 24 time zones.
• The width of each time zone is 15° of longitude.
• This means that the difference between one time zone and the next is one hour.
• Some countries would have more than one time zone with less than one hour division.
• This is considered too complicated to be useful.
• That is why some countries choose the time along one of the meridians that pass throught their territory and follow the time of that meridian for the whole country.
• This time is called standard time.

Question 13.
What is a Grid?
Answer:
A grid is a square or a rectangle that is formed between when two latitudes and longitudes out across each other. In other words, the network of latitudes and longitudes drawn on the globe is called a ‘grid’.

Question 14.
When it is 12 noon in Greenwich (0°), what is the local time at Mumbai (73° E)?
Answer:

Question 28.
“For long we have looked at the Earth as a store house of resources, which we can exploit and use at will. Gradually we are realizing the fallacy of this view point” – Interpret the above statement.
Answer:
For long we have looked at the earth as a store house of resources. With this view we recklessly exploited the earth and are responsible to the destruction of forests, rivers, hills, fellow animals and even fellow humans. This resulted in the environmental crises such as global warming and poisoning of our soils, water and air.

But gradually we understand that the earthly resources are not infinite but finite and the environmental system is a closed one. So we should not use the natural resources indiscriminately.

If a man has to survive, he must derive something from the nature. The exploitation of minimum resources from the natural environment to fulfil the basic needs of human society would cause disequilibrium of some sort in the ecological balance resulting into environmental degradation and pollution. We should always use the natural resources in such a way that they are always at available in a desired quantity and quality.

Question 29.
“Today more than any other time we need to build a new understanding of the Earth, how it works and what we do on it and what we do with each other” – Interpret the above statement.
Answer:
In the decades of 1970s there emerged a concern about the fear of depletion of natural resources because of irrational and rapacious utilization of natural resources. This serious concern arises from the fact-rapid rate of rapacious exploitation of natural resources and modern production processes and advanced technologies. Thus the exploitation of natural resources has threatened the stability and survival of natural ecosystems and existence of several plant and animal species.

Hence today more than any other time we need to build a new understanding of the earth, how it works and what we do on it and what we do with each other.

• Thus we can say the earth’s orbit is nearly circular but not exactly circular or an elongated oval path.

Question 38.
Prepare a palmphet on environmental crises.
Environment Crises
Answer:
For longtime man looked on earth as a store house of resources and tried to exploit at will. His reckless exploitation of earth has meant distruction of forests, rivers, hills, fellow animals and even fellow human beings.

Global warming, which is caused by the increased presence of green house gases like carbon dioxide, methane etc. It is resulting in melting of ice and submerging of low lands and coasts.

Soil pollution is caused by excessive use of chemicals, fertilizers and pesticides in agriculture and industrial waste deposition. Soil erosion is caused by excessive falling of trees and lack of pastures.

Water pollution is caused by routing of industrial wastes into water, usage of chemicals and pesticides etc. Air pollution is caused by the emissions from vehicles, air conditions etc.

Question 1.
How did people use the forests before the rule of the British? Why was there less danger of the forests being fully destroyed in those days?
Answer:

• The adivasis used forests for hunting, gathering tubers, fruits, flowers and herbs and for gazing their cattle.
• They cut wood, cleared the land to cultivate crops.
• They cut trees to build their homes etc.
• They did not blindly cut large tracts of forests but only small patches.
• They cut only old trees and allowed new trees to grow.
  Therefore there was less danger of the forests being fully destroyed in those days.

Question 2.
Against whom did the adivasis revolt? In what ways did they demonstrate their anger and protest? Give some examples.
Answer:

• The Adivasis revolted against the police department, the forest department and the moneylenders.
• During the protests they would burn down many police stations, posts of the forest department and houses of the moneylenders.
• In many places they would set fire to the entire jungle.
• The revolt of Santhals of Jharkhand in 1856, the Koya revolt of A.P. in 1880 and 1922, the revolt of the Maria and Muria of Bastar in 1910, etc. were some of the revolts of adivasis.

Question 3.
How were the revolts of the adivasis suppressed by the British?
Answer:

• In most of the revolts the leaders were arrested and were kept behind bars,
  e.g.: Birsa Munda died in prison in 1900.
• The leaders were traped and shot dead by the Britishers,
  e.g.: Sita Rama Raju of A.P.
• The Adivasis were armed only with bows and arrows.
• They could not stand before the gun-bearing British army.
  e.g. : In a fierce battle 15000 Santhals were killed and their revolt was finally suppressed.

Question 4.

The problems of the Indian industrialists during the British government were –

1. The British government had levied a special tax on cloth made by Indian weavers in order to help the cloth industry of Britain.
2. The British government refused to levy the similar tax on the British cloth.
3. Later the government levied a 3 /2% tax on the British goods and the same tax was levied on the cloth made in India too.
4. With this the British government made it clear that it would protect mainly the interests of the British factories.

Question 6.
During British rule, why was it easier for the European companies rather than Indian companies to set up industries? Give a few reasons.
Answer:

• Indian industry had got a little help from the British government.

Question 11.
Read the para under the title ‘Adivasi Revolts’ on page 222 and comment on it.
Adivasi Revolts :
We have seen how the conditions of the adivasi farmers who lived in the jungle worsened in British times. The Baiga, Muria, Gond and Bhil tribes of Madhya Pradeshand Chattisgarh, the Koya, Reddy, and Kolam tribes of Andhra Pradesh and the Saora adivasis of Orissa, were all no longer able to practice their old form of cultivation. They were having to become labourers for either the Forest Department or for contractors. Or they were becoming bonded labourers for moneylenders or farmers who had come from outside.
Answer:

1. As soon as the British took over Eastern India, tribal revolts broke out to challenge the alien rule.
2. In the early years of colonization, no other community in India offered such heroic resistance to British rule or faced such tragic consequences as did the numerous Adivasi communities.

Interest in concrete rail road ties increased after World War – II following advances in the design, quality and production of pre-stressed concrete. Concrete ties were cheaper and easier to obtain than timber and better able to carry higher axle weights and sustain higher speeds. Concrete sleepers have a longer service life and require less maintenance than timber due to their greater weight which helps them remain in the correct position longer.

Problems with wood ties include rot, splitting, insect infestation, plate-cutting, etc. In addition to these, the government wanted to reduce the burden on the forests.

So the concrete sleepers are introduced and replaced the wooden sleepers.

Question 1.
Name one important beverage crop and specify the geographical conditions required for its growth.
Answer:

• Tea is an important beverage crop.
• The tea plant grows well in tropical and sub-tropical climates.
• Fertile, well-drained soil, rich in humus and organic matter is essential.
• Tea bushes require warm and moist frost-free climate all through the year.
• Frequent showers are necessary.

Question 2.
The land under cultivation has got reduced day by day. Can you imagine its consequences?
Answer:

• The land under cultivation has been reducing due to the competition for land between non-agricultural uses such as housing, etc.
• As a result, the productivity of India has started showing a declining trend.
• That would lead to the scarcity of food grains in future and in turn poverty and drought situation would prevail in our country.

Question 3.
On an outline map of India show millet producing areas.
Answer:

Question 4.
What is a Minimum Support Price (MSP)? Why is a MSP needed?
Answer:
1) A Minimum Support Price is a price at which the farmers can sell their grain, if they want, to the Government.
2) The Government sets the MSP so as to cover the cost of cultivation and allow a little bit of profit to the farmer.
3) Thus the farmer, produced far markets within the country.
4) The farmers are not forced to sell their grains at cheaper prices to the traders.

Question 5.
Explain all the ways the Indian government supported the Green Revolution.
Answer:

• The Green Revolution was initially introduced in Punjab, Haryana, western Uttar Pradesh, and in some parts of Andhra Pradesh and Tamilnadu.
• The Government introduced new kinds of seeds, known as High Yielding Varieties to the Indian soils.
• It was also accompanied by use of chemical fertilizers, machinery such as tractors, and others besides irrigation facilities.
• A variety of cooperative banks were set up to provide credit to farmers so that they buy raw materials such as seeds, fertilizers, and pesticides, machinery required for modern farming.

Question 6.
Do you think it is important for India to be self-sufficient in food grain production? Discuss.
Answer:

• A large portion of our population especially children and poor communities are unable to get adequate nutrition.
• Whenever there were little rains, drought situations prevailed. This led to decrease in food production and forced government to import food grains.
• To avoid these kind of situations we should be self-sufficient in food grain production.
• A large stock of food grains has built-up with the government through Food
  Corporation of India that could be used in case of shortage and can avoid drought and famine situations in our country.

Question 7.
How is dry land agriculture different from agriculture in other areas?
Answer:

• 45% of the cultivable land which cannot easily be irrigated and depend solely on rainfall is known as dryland in our country.
• Unlike the cultivation of irrigated lands, dryland farming poses different challenges.
  a) Conserving rainfall that the area receives is the first step. This is done through watershed development programme which includes afforestation, bunding, building check-dams, and tanks.
  b) Fertility of the soil needs to be raised by adding organic manure.
  c) Farmers may also need new varieties of seeds suitable for different regions, knowledge about the best ways of growing a mix of crops on the same land etc.
  Hence farming in dryland is different from other areas.

Question 8.
Can you recall the incidents such as pesticides being found in soft drinks? How is this related to the use of pesticides? Discuss.
Answer:

• The use of pesticides is polluting underground water.
• The soft drink factories use this underground water for making soft drinks.
• Hence undissolved pesticides are seen in soft drink.

Question 9.
Why is chemical fertilizer used in new farming methods? How could use of fertilizers make soil less fertile ? What are the alternative ways of enriching soil?
Answer:

• The chemical fertilizers are used to increase production of crops.
• But the chemical fertilizers are basically made for petro-chemicals. And eventually remain in the soil.
• As a result, many micro organisms like earth worms are destroyed.
• These micro organisms increase the fertlity of the soil. But these are detroyed and hence this, in turn, affects the long run fertility of the soil.
• The alternative ways of enriching soil, like vermicompost, can be used to increase the fertility of the soil.

Question 10.
How has the Green Revolution in some areas resulted in short-term gains but longterm losses to farmers?
Answer:

• In Green Revoluton, the farmers are encouraged to pump ground water to water-intensive crops in low rainfall areas.
• This unsustainable pumping has reduced water storage in ground.
• Consequently, many wells and tubewells have run dry.
• More over the use of chemical fertilizers has also affected the long-term fertility of the soil. Hence we can say that Green Revolution has short-term gains and long term losses.

Question 11.
What could be the effects of foreign trade on farmers’ income?
Answer:

• Foreign trade could cause farmers’ income to fluctuate a lot.
• In certain years and for certain crops the farmers might gain from exports.
• In other years, farmers could lose because of cheap imports and fall in prices of farm products.
• Small farmers without much savings will not be able to bear this loss.
• They will be caught in debt trap and become poorer.
• Hence the government must be careful in allowing trade in farm products.

Question 12.
In earlier classes we have studied about land distribution. How does the following image reflect this idea? Write a paragraph about this in the context of Indian agriculture.

Answer:
In India more than 70% of the farmers are having only small and marginal holdings,
i. e., Less than 2 hectares and hence most of these farms are not viable. The small farmers cannot produce enough to meet even their basic requirements of their families. They can invest more in agriculture to increase production. They are unable to get financial assistances.
Caption : “A man of sixty acres :
A group of six feet”.

Question 13.
Read the para under the title ‘Fertilizer Problems’ on page 70 and comment on it.

Fertilizer Problems : Manure and compost contain humus and living organisms that slowly release minerals as they decompose. Chemical fertilizers provide minerals (usually nitrogen, phosphorus and potassium) which dissolve in water and are immediately available to plants, but may not be retained in the soil for long. They may be leached from the soil and pollute groundwater, rivers, and lakes. Chemical fertilizers (as well as pesticides) can also kill bacteria and other organisms in the soil. This means that some time after their use, the soil will be less fertile than ever before. Without micro-organisms, the soil will be dependent on frequent addition of more and more chemical fertilizers. The variety of nutrients which are normally produced by micro-organisms may also be reduced. Thus, in many areas, the Green Revolution has actually resulted in a loss of soil fertility and ever-increasing costs to farmers.

Answer:

• The main environmental problem associated with fertilizer use is contamination of water with nitrates and phosphates.
• Elevated nitrogen levels in drinking water.
• Environmental pollution is a significant problem. But while most of the focus is placed on polluting industries, toxins like mercury and small particle traffic pollution, a major source of environmental devastation is caused by modern food production. Far from being life sustaining, our modern chemical dependent farming methods.

– Strip soil of nutrients
– Destroy critical soil microbes.
– Contribute to desertification and global climate change, and
– Saturate form lands with toxic pesticides, herbicides and fertilizers that then migrate into ground water, rivers, lakes and oceans.

a) duration of crop
b) number of times irrigated
c) production
d) fertilisers
e) diseases
f) pesticides
Answer:
1. Paddy, sugarcane, maize, pulses are grown in our area.
2. Paddy is grown from HYV seeds and the remaining are grown from traditional seeds.
3.

	HYV Seeds	Traditional Seeds
Duration of crop	Less	More
No. of times irrigated	Least	More
Production (comparatively)	More	Less
Fertilisers	Nominal quantity	Large quantity
Diseases	Least chancess	More chances
Pesticides	Right quantity	More quantity

Question 16.
Conduct a Debate : Make the students two teams. One team should support chemical fertilizers and another should support organic farming.
Answer:
Teacher conducts this Debate.
Example : In agriculture it is better to be followed organic fertilizers.
Reasons :
Pesticides can enter the human body.
There is a chance of groundwater damage.
The use of fertilizers can reduce the natural nutrients on the soil surface, etc.

Answer:
The food grains yields grew fast between 1980 – 1990, 2000 – 2010.
The green revolution helped farmers to produce higher level of food grains.

Question 6.
Can organic farming produce enough food for all? (Text Book Page No. 72)
Answer:
If some measures are taken, I think, organic farming can produce food for all.

Question 7.
How is organic farming especially suited for small and marginal farmers? Discuss. (Text Book Page No. 72)
Answer:
Large sections of farmers in India and their land holdings are small and marginal.
Their access to external inputs is limited and their ability to improve production is low. Globalisation and the opening up of the trade barriers among the nations have resulted in the decline of agricultural prices in the local markets to the detriment of the interests of these small and marginal farmers. Thus organic farming especially is suited for small and marginal farmers.

Question 8.
Read the following table. (Text Book Page No. 66)
Number of farmers and land they possess in India (2010 – 2011)

Complete the data in the table and the explanation in the following passage below.
Majority of farmers operate only small plots of lands. A typical Indian marginal farmer has only aboutacres to cultivate. There are 924 lakh farmers so that ..(2)..% of all farmers are marginal. If we add up the number of small and marginal farmers they form …(3)..% of all farmers. However, even though in percentage terms medium and large farmers is small, the number in absolute terms is large. ..(4)…lakh farmers can be together considered to be in this group. They have a powerful voice in rural areas. This group of large and medium farmers together operate …(5)…% of the land. Each large farmer for example on an average operates ..(6)..acres of land. Compare this with each marginal farmer who operates on an average ..(7)..acres of land. This inequality in distribution of land explains the inequalities in opportunities that they experience, the pov¬erty or growth opportunity that they face.

1. In self employment, people create their own employment and earn their livelihood. They do not depend either on government or an any other persons for their livelihood.
e.g.: Working in their own farms, opening a shop or public telephone booth or establishing a small organization like manufacturing of candles, matchboxes, etc.

2. On the other hand, some people cannot create their own employment. They generally depend either on government or on any other organization or a person for earning their livelihood.
e.g.: Working in the fields or others, or in a shop or working as government servant, etc.

Question 10.
Do you think that some families who were earlier cultivators are becoming agricultural labourers now? Discuss. (Text Book Page No. 65)
Answer:
Reasons:

1. Small land holdings
2. Dependency on seasons for rainfall
3. High rate of interests on loans
4. Very low minimum support price
5. Lack of technology
6. Big families and
7. Some rituals.
   All these changed the cultivators as agricultural labourers.

Question 11.
In which areas were the new methods of agriculture first tried? Why was the whole country not covered? (Text Book Page No. 68)
Answer:
1. The new methods were initially implemented in Punjab, Haryana, western Uttar Pradesh and in some districts of Telangana, Andhra Pradesh and Tamilnadu.

2. The HYV seeds required a lot of water and these areas were already irrigated.
Hence the new methods were introduced in these areas.

Question 12.
Why are different methods necessary for dry land areas? (Text Book Page No. 68)
Answer:

• 45% of the land which cannot be irrigated are known as dry lands.
• It would be very difficult and expensive to irrigate these dry lands.
• These areas must depend solely on rainfall.
  Hence different methods are necessary for dry land areas.

Question 13.
How increase in buffer stock would help to avoid situations of drought and famines? (Text Book Page No. 69)
Answer:

• A large stock of food grains should be maintained with the government.
• That buffer stock could be used in case of shortage of food grains and can also be used to supply foodgrains to inaccessible areas.
• We can also avoid drought and famine like situations in our country.

Question 14.
How farmers were able to raise higher amount of food grains on the same plot of land over the years? (Text Book Page No. 69)
Answer:
The use of High Yielding Varieties of seeds, chemical fertilizers, machinery, etc. made the farmers to raise higher amount of food grains on the same plot of land over the years.

Question 15.
Why did not the Indian government allow farmers to export foodgrains during the Green Revolution years? (Text Book Page No. 71)
Answer:
There would be a shortage of food grains if the government allows farmers to export food grains. So the government did not allow farmers to export food grains.

Question 16.
Why should government ban exports /import ? How does this policy help Indian farmers? (Text Book Page No. 71)
Answer:
Foreign trade could cause farmers income to fluctuate a lot. In some years farmers could lose because of cheap imports and fall in prices of farm products. So the exports ad imports should be banned.

Small farmers will not be able to bear this loss. They will get caught in debt trap and become poorer. So this ban helps the Indian farmers in preventing them from debts and heavy losses.

Question 17.
Use an atlas of India to find the locations of the below mentioned dams and mark them on a map of India. Also label the names of the major rivers on which these dams were built. (Text Book Page No. 67)

Question 1.
Life itself constitutes a separate sphere called ‘Biosphere’. Explain.
Answer:

• The Earth is a unique planet, in that it has life.
•  It is inhabited by countless forms of life from microscopic bacteria to great banyan trees and animals like lions and blue whales and of course human beings.
• The earth has a combination of land, air, and water, and a moderate temperature has made life possible on it.
• Various forms of life are not only related to the three spheres around them, but also to one another.
• They influence one another and they are part of a complete “food chain.”
• Hence geographers are of the opinion that “life itself constitutes a separate sphere called ‘Biosphere’.

Question 2.
Why is ecological crisis created in modern times? What are its effects?
Answer:

• These days the increase in population creates great pressure on earth as well as its resources.
• To satisfy the needs of ever growing population systematic mining, cutting of forests, building of forests and fields and roads took place all over the earth.
• Burning of fossil fuels and release of enormous amounts of waste materials by industries contaminate air, water, and soil.
• For providing food for the ever growing population, there is a need for increase in agricultural production.
• Modern agriculture uses a large amount of chemical fertilizers and pesticides.
• The most frightening aspect of pollution due to modern agriculture is the increase in the levels of toxins in our food.
• This increasingly proves to be very harmful not only to humans but also to all types of life on earth.
• Since all living and non-living things on the earth are in one way or the other connected to each other, change affecting one, in due time affects all the others too. All these factors lead to ecological crisis.

Effects of ecological Grisis :

1. If a particular species which feeds upon a particular kind of plant is exterminated, it would result in unchecked growth of that plant and it may intrude the area where other plants grow and disturb their growth.
2. Many industries use chemicals and metals which flow into the rivers and streams. The metals like mercury are consumed by microorganisms in water and in turn beome the food of fishes. When human beings consume these fishes they too absorb some amount of mercury which is detrimental to their health.
3. Farmers use Diclofenac to treat cattle; when the cattle die their flesh retains this chemical: When their flesh is consumed by vultures, diclofenac leads to kidney failure in them and they die.

Question 3.
Natural vegetation depends upon the climate of the place. Write different kinds of forests and climatic conditions of their existence?
Answer:
a) Tropical Deciduous Forests :

1. Tropical deciduous forests are the monsoon forests.
2. These regions experience seasonal changes.
3. Trees shed their leaves in the dry season to conserve water.

b) Tropical Evergreen Forests :

1. These thick forests occur in the regions near the equator and close to the tropics.
2. These regions are hot and receive heavy rainfall throughout the year.
3. As there is no dry season, these trees do not shed their leaves altogether.
4. This is why they are called evergreen forests.

c) Temperate Evergreen Forests :

1. These forests are located in the mid latitudinal costal region.
2. They are commonly found along the eastern margin of the continents.

d) Temperate Deciduous Forests :

1. The temperate deciduous forests are found in higher latitudes.
2. They shed their leaves in the dry season.

e) Mediterranean Vegetation :

1. The west and the south west margins of the continents are covered by these forests.
2. Mediterranean trees adapt themselves to dry summers with the help of their thick barks and wax coated leaves. These help them to reduce transpiration.
3. These regions are marked for hot dry summers and dry summers and mild rainy winters.

f) Coniferous Forests :

1. Coniferous forests are found in the higher latitudes of Northern hemisphere.
2. These forests are found in abundance in the Himalayas.

g) Tropical Grasslands :

1. These forests grow on either side of the equator up to tropics.
2. This vegetation grows in the areas of moderate to low amount of rainfall.

h) Temperate Grasslands :

1. These are found in mid-latitudinal zones and in the interior part of the continents.
2. Usually the grass is very short and nutritious.

i) Thorny Bushes :

1. These are found in the dry desert like regions.
2. This vegetation cover is scarce here because of scanty rain and scorching heat.

j) Tundra :

1. This vegetation is found in the polar region.
2. The growth of natural vegetation is very limited here.
3. Only mosses, lichens and very small shrubs are found here.

Question 4.
How can we protect natural resources?
Answer:
Preservation of the natural environment is essential for maintaining community sustainability.
1. Water:
Communities must work to assure an adequate water supply to meet future needs.

2. Energy :
Energy should be consumed reasonably.

3. Air and climate :
Communities can preserve air quality by limiting or eliminating the discharge of harmful chemicals into the air and by minimizing the sources of air pollution.

4. Biodiversity :
Healthy wildlife should be supported through integrative approaches for, managing, protecting, and enhancing wildlife populations and habitats appropriate to their area and the atmosphere.

5. Land, forests, ecosystems should be provided protective measures. Thus we can protect natural resources.

Answer:

Question 7.
Read the paragraph under the title ‘Depletion of Resources’ on page 57 and comment on it.

Industrialisation, rapid population growth and urbanisation all have meant unprecedented exploitation of natural resources like minerals, forests, soil, water, air etc. besides sources of energy (coal, petroleum etc.) stored in the earth for billions of years. This has resulted in rapid deforestation and decline of reserves of minerals, oil and ground water. Many scientists have argued that the present way of life is not ‘sustainable’for if we use so much natural resources, nothing will be left for our children and grand children.

Answer:
Depletion of resources is the consumption of a resource faster than it can be replenished.

Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion.

Resource depletion is most commonly used in reference to farming fishings mining, water and fossil fuels.

9th Class Social Studies 5th Lesson Biosphere InText Questions and Answers

Question 1.
Can you say how plants are dependent upon air and water and how they affect the two in return? (Text Book Page No. 51)
Answer:

• Plants need water. Plants use water to carry moisture and nutrients from the roots to the leaves and food from the leaves back down to the roots.
• Plants absorb carbon dioxide from air to form carbohydrates during the process of photosynthesis.
• Nitrogen gas molecules that are trapped and carried in the water droplets provide nourishment to plants.
• Plants need oxygen in small amounts in respiration.
• Plants reduce the carbon dioxide levels in atmosphere and reduce the greenhouse effect and in turn the global warming.

How do plants affect water and air in return?
Answer:

• Plants return water to the atmosphere through the process of transpiration.
• Transpiration is the evaporation of water from aerial parts of plants, especially from . leaves but also from stems and flowers.

Question 2.
In what ways are insects like mosquitoes and butterflies dependent upon rocks or soil and upon water ? How do they affect them in return? (Text Book Page No. 51)

Mangoes, Guavas, Blackberry are fruit bearing trees. In addition to them we have coconut trees and trees which give us drumsticks.

Question 6.
Can you discuss how human beings would have impacted the land, water, plants and animals around them when they began agriculture and animal herding? (Text Book Page No. 56)
Answer:

• With the development of agriculture humans began to radically transform the environment in which they lived.
• They cleared the lands around their settlements and controlled the plants that grew and the animals that grazed on them.
• They devised ways of storing rain water and rechanneling river water to irrigate plants.
• They built reservoirs, dug canals, dikes and sluices that permitted water storage.
• They domesticated major food crops, plants such as flax and cotton and began to cultivate them.
• Men also took lead in taming, breeding and raising the large animals associated with both farming and pastoral communities.
• Thus human beings impacted the land water, plants and animals around them when they began agriculture and animal rearing.

Question 7.
What sources of energy would they have used and how would they haveobtained them? (Text Book Page No. 56)
Answer:

1. The growth of sedantary farming greatly accelerated the pace of technological and social change.
2. Still the man used the physical energies of human and animals to use the agricultural and manufacturing tools.
3. He used wheel to make pots, plough to plough his fields and boats to transport his goods and kiln of blacksmith to make his tools.
4. He burnt firewood to cook his food.
5. Thus when they began agriculture man used merely the physical energy of human beings and animals.

Question 8.
Can you say what kinds of changes will building of cities have on the land and water around them? (Text Book Page No. 56)
Answer:

• With the beginning of agriculture and use of better tools give rise to larger, more elaborate and commodious housing and the construction of community ritual centres.
• Sun-dried bricks, interwoven branches usually plastered with mud and stone structures were associated with early agricultural communities.
• Houses in early agricultural settlements included special storage areas. They were centered on clay or stone hearths that were ventilated by a hole in the roof.
• To defend their cities from the rival nomadic settlements, they fortified their cities.
• The people had devised ways of storing rain water and rechanneling river water to irrigate plants.
• The reservoirs and canals, dikes and sluices that permitted water storage were constructed.

Question 9.
In what way do you think this would have affected the land scape and water cycle? (Text Book Page No. 56)
Answer:

• The increase in population create great pressure on earth as well as its resources.
• The entire earth was reshaped to suit the needs of humans.
• The surface of the earth received a great push with the industrial revolution and process of colonization.
• Industrial production needs raw materials on an unprecedunted scale.
• Industrial countries began to search for diverse kinds of raw materials and sources of energy.
• They dug deep wells and tried to find out what lay underneath.
