4. Give reasons:

  1. There is scanty vegetation in the deserts.
  2. People of the Sahara desert wear heavy robes.

Answer:

  1. There is scanty vegetation in the deserts because of the following reasons:
    • Vegetation depends on two factors: climate and soil.
      • The climate in the deserts is either very hot and dry or very cold and dry.
        ★ Such a climate does not allow the growth of vegetation.
        ★ Rainfall is scanty. Hence vegetation does not grow in dry conditions.
      • Soil is either sandy (in hot deserts) or covered with snow (cold deserts) for most of the year. Both types of soil do not encourage vegetation to grow.
  2. People of the Sahara Desert wear heavy robes because of the following reasons:
    • Robes of the people of Sahara Desert are made of hides (of animals) or hair of animals.
    • These robes are heavy:
      • They protect the people from the scorching sun and extreme heat (dust storms and hot winds).
      • They protect the people from dust storms and hot winds.
