Which of the following functions performed by a forest help most in controlling drought?

  1. Forests prevent soil erosion

  2. Forests bring rainfall

  3. Forest have lot of water plants

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Forests help mitigate drought by increasing local humidity and rainfall through transpiration, and by preventing soil erosion, which maintains the soil's water-holding capacity. Since both statements A and B are correct, D is the best choice.

What happens when rain falls on soil without vegetational cover?

  1. Rain water percolates in soil efficiently

  2. Rain water causes loss of surface soil

  3. Rain water leads to fertility of the soil

  4. Rain water does not cause any change in soil
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vegetation cover on the ground helps to hold the soil in place. It also helps in percolating water into the deeper layers of the soil. The absence of vegetational cover may lead to soil erosion.

So, the correct answer is option B.
