Question

(a) By reducing in the sunlight penetration

(b) By reducing the rainfall’s force on the soil’s surface

(c) By reducing the pressure

(d) By increasing the rainfall’s force on the soil’s surface

I got this question in an online quiz.

Query is from Forest Ecosystems in chapter Ecosystems of Energy Management

Answer 1

Right answer is (b) By reducing the rainfall’s force on the soil’s surface

Easy explanation: Forest prevents erosion by reducing the rainfall’s force on the soil’s surface. Forest absorbing water and they do not allow it to flow directly run off. By this method, they prevent the removal of topsoil.
