AP State Syllabus 7th Class Social Important Questions 4th Lesson Oceans and Fishing<\/h2>\n

Question 1.
\nFishing with the mechanical boat is risky than the Karratheppa. Why?
\nAnswer:
\nCompared to the Karrateppa, there is far more risk of life in Marapadava (Mechanised boat) because it goes far into the sea and it is difficult to swim over to shore in times of trouble.
\nWhat is worse, there is no first aid in the big boats, nor any life jacket. Fishing is a risky and brave occupation.<\/p>\n

Question 2.
\nStudy the table given below and answer the following questions.
\nDistribution of Fresh Water on Earth<\/p>\n\n\n\n\n\n\n\n
Sl.No.<\/td>\nSource<\/td>\nPercentage<\/td>\n<\/tr>\n

Question 4.
\n“The lives of fishermen are risky and troublesome” – Comment in your own words.
\nAnswer:
\nI agree with the above statement.<\/p>\n

    \n
  1. Most of the Fishermen do not own mechanical boats. They depend on others boats and go fishing.<\/li>\n
  2. Always they are taking money from middlemen for diesel and kit expenses.<\/li>\n
  3. Again they sell the day\u2019s catch of fish to the middlemen at the rate he fixes.<\/li>\n
  4. They don\u2019t have any profits.<\/li>\n
  5. There is no First Aid in the big boats nor any life jacket.<\/li>\n<\/ol>\n

    Their life is risky and troublesome. While they go fishing, if any cyclone hits that area, they are not able to reach the coast of the ocean.<\/p>\n

    Question 5.
    \nWhat is an ocean? Name the oceans in the world.
    \nAnswer:
    \nThe vast body of salt water that covers a considerable portion of the earth\u2019s crust is called the ocean. There are three major oceans in the world. They are the Pacific, the Atlantic, and the Indian ocean. Apart from these three, waters of the Arctic and Antarctic are also described as oceans.<\/p>\n

    Question 6.
    \nWhat are the two types of ocean currents? Give examples.
    \nAnswer:
    \nOcean currents are of two types. They are:
    \n1) Warm currents: They flow from the equator towards poleward regions.
    \nEg: The Gulf stream and the Atlantic drift.
    \n2) Cold currents: They flow from poleward regions towards the equator.
    \nEg: The Labrador current, The Greenland current.<\/p>\n

    \"AP<\/p>\n

    Question 7.
    \nWhat are high tides and low tides?
    \nAnswer:
    \nHigh tide: The bulge of seawater is high tide.
    \nLow tide: The level of the seawater reduces. It is low tide.
    \nHigh tides and low tides occur twice each day.<\/p>\n

    Question 8.
    \nExplain the different types of nets.
    \nAnswer:
    \nNets are of different types based on different sizes of the Kannulu (Rings) and the layers of the net. Recently a net known as Ring Net which helps in getting a better catch is being increasingly used by the fishermen. This has helped to reduce migration from the village. Earlier there were nets made up of cotton thread. Now cotton nets have almost been replaced by plastic, nylon and other synthetic, materials. A net lasts for 4 – 5 years. Nets are purchased by weight and the type of rings they contain. Nets cost around Rs. 250-300 per kg. Ring nets weigh around 500 kgs.<\/p>\n

    Question 9.
    \nWhat enables the middlemen in the fish business to earn much more money than the fishermen?
    \nAnswer:
    \nSome middlemen temporarily store the fish, segregate them and carry them in cold container tanks to faraway places like Kolkata, Bangalore, Chennai, Hyderabad, Kerala, and so on. These people get four times more money than the catcher does. They also provide advances for the fishermen with interest. Fishermen have no option to sell the day\u2019s catch of fish to the middlemen at the rate they choose to fix. Thus middlemen earn more money than fishermen.<\/p>\n
