Question 6.
\nWhat is weak zone or fault zone? Name some of these zones in India.
\nAnswer:
\nSince earthquakes are caused by the movements of plates, the boundaries of the plates are the weak zones of fault zone, where earthquakes are more likely to occur. In India, the areas most threatened are Kashmir, Western and Central Himalayas, the whole of North-East, Rann of Kachchh, Rajasthan and the Indo-Gangetic Plain. Some areas of South India also fall in the danger zone.<\/p>\n

\"Some<\/p>\n

Question 7.
\nWhat is a Richter scale? Is it linear? What are the magnitudes of earthquakes that can cause severe damage to life and properties?

Some Natural Phenomena Class 8 Extra Questions Long Answer Type<\/h3>\n

Question 1.
\nWhat are the suggestions that can be followed to protect buildings against earthquakes?
\nAnswer:
\nGiven below are the suggestions that can be followed to protect buildings against earthquakes :<\/p>\n

    \n
  1. The buildings should be so designed that they become \u2018Quake Safe\u2019. For this purpose, qualified architects and structural engineers should be consulted.<\/li>\n
  2. In highly seismic areas, the use of mud or timber is better than using heavy construction material. Roofs should be kept as light as possible. In case the structure falls, the damage will not be heavy.<\/li>\n
  3. Cupboards and shelves should be fixed to the walls, so that they do not fall easily.<\/li>\n
  4. Since some buildings may catch fire due to an earthquake, it is necessary that all buildings, especially tall buildings, have fire fighting equipment in working order.<\/li>\n<\/ol>\n

    Question 2.
    \nWhat steps should be taken for protection if an earthquake strikes ?
    \nAnswer:
    \nIn the event that an earthquake does strike, the following steps should be taken for protection:
    \n(A) At home:<\/p>\n

      \n
    1. One should take shelter under a table and stay there till shaking stops.<\/li>\n
    2. One should stay away from windows.<\/li>\n
    3. One should stay away from tall and heavy objects that may fall on him\/her.<\/li>\n
    4. If anybody is in bed, he\/she should not get up but protect his\/her head with a pillow.<\/li>\n<\/ol>\n

      (B) Outdoors :<\/p>\n

        \n
      1. One should find out a clear spot away from buildings, trees and overhead powerlines and drop to the ground.<\/li>\n
      2. If anybody is in a car or a bus, he\/she should not come out. Instead the driver should be asked to drive slowly to a clear spot and should not come out till the tremors stop.<\/li>\n<\/ol>\n

        Question 3.
        \nWhat are the causes of earthquakes? Describe the major cause.
        \nAnswer:
        \nCauses of earthquakes:
        \n(i) Movement of the earth\u2019s plates (major cause): The outermost layer of the earth is not in one piece. It is fragmented. Each fragment is called a plate. These plates are in continued motion. The boundaries of the plates are the weak zones, where earthquakes are more likely to occur due to sliding of one plate over or below the other. The weak zones are also known as seismic or fault zones.
        \n(ii) Volcanic eruption.
        \n(iii) Underground nuclear explosion.
        \n(iv) When earth is hit by a meteor.<\/p>\n
