Question

What is the effect of rain on soil without a vegetational cover?

• A. Rain water percolates in soil efficiently
• B. Rain water causes loss of surface soil
• C. Rain water leads to fertility of the soil
• D. Rain water does not cause any change in soil

Answer 1

The correct option is B

Rain water causes loss of surface soil

When rain falls on soil without vegetational cover, it causes soil erosion as the top layer of the soil is eroded by water. Topsoil is the most fertile layer of soil because it contains the most organic, nutrient-rich materials.
