AP State Board Syllabus 7th Class Social Studies Notes Chapter 5 Europe

→ Industrial Revolution took place first in Europe.

→ The Mediterranean sea separates Europe from North of the Africa.

→ Asia and Europe are one continuous landmass. This landmass is therefore called Eurasia. & Europe has several high snow-covered mountains.

→ The Alps, the most important mountain ranges of Europe, are covered with snow all year round.

→ The Caucasian Mountains, which lie between the Caspian Sea and the Black Sea, form the southern boundary of Europe.

→ There are no large plateaus in Europe.

→ European rivers are used not only for irrigating the fields but also as major waterways; & The sea coast of Europe is very jagged.

→ Landmasses that are surrounded by the sea on three sides and connected to the mainland on the fourth side are called peninsulas’.

→ The Landmass which is surrounded by water on all sides is called an Island.

→ Bays and gulfs are parts of the sea enclosed by land on three sides.

→ Deep gulfs or bays are preferred for building harbors as large ships can be anchored in them. & Europe has a cooler climate than ours.

→ The waters in the oceans are not static.

→ The warm currents are very good for fish breeding as they contain ample food materials for the fish.

→ The lands along the Mediterranean Sea have a distinct climate called the ‘Mediterranean climate’. & Most European countries including France have four main seasons. They are winter, spring, summer, and autumn.

→ Summer is the season of agriculture in Europe. Crops mature in this season.

→ In European countries, cultivation is possible only for 6 to 7months.

→ European plains and river valleys are very fertile.

→ Wheat is the main crop of European plains.

→ From very ancient times, the people of Europe have been trading with India and other countries of Asia like Indonesia and China.

→ About five hundred years ago, the West European sailors and traders began to search for new routes to India. The industrial revolution as you know started in England around 1750.

→ Peninsula: Landmass that is surrounded by the sea on three sides and is connected to the mainland on the fourth side is called Peninsula. E.g.: Norway and Sweden.

→ Island: A piece of land that is completely surrounded by water is called an Island. E.g.: Great Britain.

→ Since long ago, man has used animals not only for obtaining food but also for agriculture.

→ People living in rural areas used to domesticate animals like cows, buffaloes, bullocks, goats, sheep, pigs, hens, etc.

→ Bulls are mainly reared for use in plowing.

→ Taking care of animal health is also an important task in animal husbandry.

→ Viral and bacterial diseases also affect milk production.

→ Veterinary doctors provide treatment and health care for cattle.

→ Our government treats producing milk as an industry.

→ Haryana, Jaferabad, Nagapuri are the traditional varieties of cows that give a good quantity of milk.

→ According to the Economical and Statistical Survey of India 2011, about 40 to 60 lakh liters of milk are produced every day in our state.

→ Care should be taken while buying cattle for milk production.

→ Biogas production also is a useful product in animal husbandry.

→ Production and rearing of hens on a large scale are generally called poultry.

→ The culture of honey bees is called Apiculture.

→ The bee wax and bee venom are other products in Apiculture.

→ Fish constitute important and plentiful sources of high-quality animal protein.

→ The egg is the chief nutritious food that is easily available for all.

→ Our government provides opportunities to improve animal food production to fulfill the food requirements of a growing population.

→ Animal husbandry: Providing food, shelter, protection, and breeding of animals is called Animal husbandry.

→ Livestock: The term represents cows, bulls, and buffaloes.

→ Jersy, Holstein: Jersy (England) and Holstein (Denmark) are the foreign varieties. They give 25 liters of milk per day.

→ Pasteurization: In this process, milk is heated at a temperature (62°) for a definite period of time (30 minutes) and cooled at 10CC.

→ Biogas: The dung obtained from cattle is mixed with bacteria and ¡s used for the production.

→ Poultry: Production and rearing of hens on a large scale for eggs and chicken.

→ Hatching: Placing the egg under a broody hen to produce chicken is hatching.

→ Incubator: An apparatus for hatching eggs.

→ Apiculture: The culture of honey bees is called apiculture.

→ Honey bee hive: A construction of six-sided wax compartments made by bees to store honey and eggs.

→ Honey wax: Besides honey wax produced by the honey bees is known as bee wax or honey wax used ¡n the production of cosmetics, shoe polish, candles, and leather industry.

→ Queen bee: Only one Queen bee in a colony. The function is to lay eggs. (800 – 1200 per day)

→ Drone: Drones are the male members of the honey bee colony. Their main duty is participating in mating.

→ Aquaculture: Cultivating fish and prawns in water on a large scale.

→ Marine fisheries: India’s marine fisheries sources include 7500 km of coastal line and deep seas beyond it. Popular marine fish varieties include Mackerel, Tuna, Sardines, and Mumbai duck.

→ Inland fisheries: In such a system, a combination of five or six fish species is used in a single fish pond. These species are selected so that they do not compete for food among them and have different types of food habits.

→ Breeding: Mate and then produce young.

→ Food processing: Preservation of food items through the processing of sun-drying semi-drying, salting and drying, pickling, and pit curing.

→ Milk is the secretion of the mammary glands in animals. During the period following at least 72 hours after calving or until the milk is colostrum free, milk appears as white opaque fluid, in which fat is present as emulsion, protein, and some other minerals, vitamin A, D, and E are 80 to 90% of water. Nowadays cattle rearers and dairy farmers use hormone injections to get a high quantity of milk. These hormones settle down in our body to cause various diseases like early reaching of puberty. Chemicals used in chilling centers to preserve milk also cause damage to our health.

→ In Odisha traditional livestock – Chilka buffaloes are reared. They take care to avoid cross-breeding with Murra. They graze during night times in the brackish water of Chilka lake. They return home in the morning give milk without any extra feed. This milk

→ Emu is a flightless bird from Australia. It is the second-largest bird in the world after Ostrich. This amazing bird weighs nearly 50 kg. and run at 40 miles per hour.

Meat, chicks, skin leather, oil, feathers eggs are the main products in the Emu culture. Its meat and eggs are costly. The Emu market is not so good at present in our state.

→ Honey has probably been associated with man since very early days. The first proof of this association is evident from the rock paintings made by primitive man thousands of years ago. The man knows about the art of beekeeping in the regions of early civilization. The Egyptians were well acquainted with bee husbandry 4000 years ago as they practiced migratory beekeeping. The Rigveda, probably written between 3000 B.C. and 2000 B.C, contains many references to bees and honey. They named honey as a divine food.

→ Seaweeds constitute an important marine resource and are found along the Rocky intertidal and sub-tidal regions of the coasts of India. The Sunderbans, the Chilka lake, the deltas of Godavari and Krishna, Gulf of Mannar, Palk Bay, Gujarat coast, and around Lakshadweep, Andaman, and Nicobar Island are areas rich in seaweeds. They are used for human consumption, as cattle and poultry feed, as manure, and for industrial purposes as the sources of Phyco colloids like Agar-agar.

AP State Board Syllabus 7th Class Social Studies Notes Chapter 4 Oceans and Fishing

→ The earth is known as a watery planet as it is the only planet containing water in abundance. & It is estimated that about 71% of the earth’s surface is occupied by seas and oceans.

→ An extension of saline water on earth is called the sea.

→ Large sea areas are called oceans.

→ Oceans are huge bodies of water generally separated by continents.

→ The floor of the ocean is just like the surface of the earth.

→ The bottom of the sea is not a flat surface.lt consists of hills, mountains, plateaus, plains, trenches, etc.

→ The waters of the oceans are never still.

→ Ocean waters have three kinds of movements. They are:

1. Waves,
2. Currents,
3. Tides. & Streams that flow constantly in a definite direction on the surface of the ocean are called ocean currents.

→ The ocean currents are of two types – the warm currents and the cold currents.

→ Tides are the rhythmic rise and fall in the level of the water in the oceans every day.

→ Tides do not rise to the same height every day.

→ Ocean water is always saline. It contains Several mineral salts dissolved in it.

→ The oceans are the main source of rainfall.

→ Oceans are storehouses of fish and other seafood.

→ They are the main source of salts.

→ Oceans provide natural highways for international trade.

→ The fishermen have a special tool kit for repairing the nets which consist of Nulukarralu Nulukanda and a flattened stick that determines the net ring size.

→ The village soil is mainly loamy and rice is the principal crop grown on it.

→ A large number of people of Bhavanapadu worship Gangamma, Gowri, and Shiva

→ Tool kit: The fishermen have a special tool kit for repairing the nets which consist of Nulukarralu (net repairing fork) N.ilukanda (thread) and a flattened stick that determines the net ring size.

Students can go through AP State Board 7th Class Social Studies Notes Chapter 3 Tanks and Ground Water to understand and remember the concept easily.

AP State Board Syllabus 7th Class Social Studies Notes Chapter 3 Tanks and Ground Water

→ The Kakatiya and Vijayanagara kings and Nayaks built a large number of tanks in Telangana and Rayalaseema. This enabled the extension of agriculture into these areas.

→ The tanks were usually built by building a strong wall of stones and mud across a small stream in such a way that with a wall on just one side a large lake could be formed.

→ The tanks helped the people not only in giving them and their animals drinking water but also in irrigating their fields in such a way that even in drought years they could raise at least some crops.

→ Most important thing is that the tanks helped to prevent the run-off of rainwater and the erosion of topsoils.

→ During the last twenty or thirty years, the tanks have been neglected and have been allowed to break down.

→ Rocks that have cracks or pores in them and can contain water are called previous rocks. & Rocks like granite, Kadapa limestone, are very compact and do not have pores in them.

→ Water cannot enter into them. These are called impervious rocks.

→ The layer of water which accumulates under the ground among rocks is called an aquifer.

→ The level of groundwater, which is also called the water table.

→ Most of the rocks under the soil in Andhra Pradesh consist of granites, which are hard and impervious.

→ If we draw more water than what percolates down, the groundwater will decrease over time.

→ Vegetation like trees, grasses, and bunds are used to enhance groundwater.

→ Groundwater is usually mixed with many minerals.

→ Many times water Is polluted due to the excessive use of fertilizers, pesticides, or poor drainage.

→ Groundwater like the rivers is the common resource of all people and not just of those who have landed over aquifers.

→ Those who own land over aquifers tend to over-use the water, which decreases the water table for all neighboring people.

→ Today’s generation has received water from the past as a sacred asset. We should give it to the future generation just as we received it.

→ Previous rocks Rocks which have cracks or pores (minute holes) in them and can contain water are caLled pervious rocks

→ Impervious rocks: Some rocks like granite, Kadapa limestone, are very compact and do not have pores in them. Water cannot enter into them. Groundwater usually accumulates above such rocks Since the water can’t go beneath them, these are caLled impervious rocks

→ Vegetation: The vegetation means trees and grasses and buns etc.

→ Aquifers: The layer of water which accumulates under the ground among rocks is an aquifer.

→ Megalithic age: The stone boulders are known as megaliths. These were arranged by people and were used to mark burial sites.

→ Water table: The level below which the ground is saturated with water.

→ Tanks: The tanks were usually built by building a strong wall of stones and mud across a small stream in such a way that with a wall on just one side a large lake could be formed.

→ Groundwater: Rainwater that goes down into the soil accumulates below the ground in the gaps between rocks, pebbles, sand, etc. This is the groundwater.

→ Minerals: The minerals like Sodium, Fluoride, Chloride, Iron, Nitrate, etc., come from the rocks and soils underneath

Students can go through AP State Board 7th Class Social Studies Notes Chapter 2 Rain and Rivers to understand and remember the concept easily.

AP State Board Syllabus 7th Class Social Studies Notes Chapter 2 Rain and Rivers

→ All life on the earth is very crucially dependent upon water.

→ As you know over 71% of the earth’s surface is covered with water.

→ We depend upon water for growing crops. But we do not get water uniformly over the year.

→ After the unbearable heat of April, May and June, comes the rainy season, which lasts for a few months.

→ Water in the cloth or in the plate becomes water vapour and mixes with the air through a process called ‘evaporation’.

→ There are several water bodies on the earth’s surface – oceans, rivers, lakes etc.

→ There is constant evaporation of water from these water bodies.

→ Formation of clouds and Rain: When water vapour rises with hot air and reaches high up in the sky, it gets cooled. This is because it gets cooler as we rise above the surface of the earth. With the cooling, water vapour is transformed into tiny water droplets. Change of water into vapour is known as evaporation.

→ The process of water evaporating from the seas, forming clouds in the sky, coming down like rain. Different forms of condensation of water vapour are known as precipitation.

→ The amount of invisible water vapour present in the atmosphere is known as humidity. The winds come all the way from the Arabian Sea and the Bay of Bengal and they transport the rain clouds. They are called ‘Monsoon winds’. They are also called ‘south-west monsoon winds’ as they blow from that direction. These winds blow only in the summer.

→ There are two arms of the monsoon winds: one blows from the Arabian Sea and the other from the Bay of Bengal.

→ The southwest monsoon, however, brings much rain to the Telangana districts as the winds again rise over the Eastern Ghasts.

→ In the months from May to October, cyclones form in the Bay of Bengal causing widespread rains in coastal and inland Andhra Pradesh.

→ Rain caused by whirling storms is called cyclonic rain.

→ The cyclones are formed in the sea due to intense heating up in summer.

→ An instrument by which the rainfall is measured is known as ‘rain gauge.

→ The amount of rainfall for a unit area is measured in centimetres.

→ Rivers or streams which join a larger river are called ‘tributaries’.

→ Rivers like the Krishna and the Godavari start from the Western Ghats, which receive heavy rains.

→ The treeless bed is called the floodplain of the river.

→ Vegetation covers on land obstruct the runoff rainwater and slow down the speed of its flow. Vegetation reduces the erosion of soil by rainwater.

→ If the surface of the land is covered with vegetation, then soil erosion is greatly reduced. The worst cyclone hit the state in November 1977.

→ Recently in 2018 Titles cyclone created huge destruction in North coastal Andhra, Srikakulam.

→ Cyclones and floods are seasonal phenomena.

→ Rivers and Tributaries: A river is usually in the form of a thin stream. As it flows further it gets bigger and broader. This happens because many small streams join it as the stream flows. Rivers or streams which join a large river are called tributaries

→ Condensation: Drops of water that form on a cold surface when warm water vapour becomes cool.

→ Annual rainfall: In the months from May to October cyclones form in the Bay of Bengal causing widespread rains in coastal and inland Andhra Pradesh.

→ Flood plain: Every year when it rains heavily, the river trough is filled with water allowing no permanent trees or plants to grow there. This treeless bed is called the flood – plain of the river.

→ Cyclone: A violent tropical storm in which strong winds move in a circle.

→ Monsoon: The rainy season.

→ Hail: ice pieces of frozen vapour falling in showers.
