Question

What happens when rain falls on soil without vegetational cover?

Options

• Rainwater percolates in soil efficiently

• Rainwater causes loss of surface soil

• Rainwater leads to the fertility of the soil

• Rainwater does not cause any change in soil

Answer 1

Rainwater causes loss of surface soil

Explanation:

Vegetational cover plays an important role in preventing soil erosion. The roots of the plants hold the soil particles in place. These also play a role in the percolation of water into the deeper layers too. Thus the absence of vegetational cover will cause the removal or displacement of the upper layer of soil, a process called soil erosion.
