Question

What happen when rain falls on the soil which is devoid of vegetation cover?

• A. Rainwater percolates into soil efficiently.
• B. Rainwater causes loss of surface soil.
• C. Rainwater leads to fertility of the soil.
• D. Rainwater does not cause any changes in the soil.

Answer 1

Answer: (B)

Rainwater causes loss of surface soil.

During heavy rainfall, trees act as natural absorbers. The roots of trees hold the soil tightly and prevent its erosion, thereby reducing sediments going into rivers and increasing water absorption into the ground. But when the soil is without vegetation cover, the rainwater carries away the soil and causes its loss. Thus, the correct answer is option B.
