Question

What happens when rain falls on soil without vegetation cover?

A. Rainwater percolates in soil efficiently 

B. Rainwater causes loss of surface soil 

C. Rainwater leads to fertility of the soil 

D. Rainwater does not cause any change in soil

Answer 1

Soil without vegetation cover is like a body without an immune system. Any natural or man-made activity can easily drain away from the topmost region of soil thus making a barren land. The same is the case here, rain will take away most of the soil along with it thus causing soil erosion.
