Soil erosion can be prevented by ________
A
Allowing herbivorous animals to graze freely
B
Growing plants on a large scale to form soil cover
C
Making the land sloppy
D
Adding chemicals to increase cohesion
Correct Answer: Growing plants on a large scale to form soil cover
Soil erosion can be prevented by growing plants on a large scale to form soil cover. Soil cover with living plants (soil can also be covered with mulch) protects the soil surface from rain, wind and sun. It reduces soil erosion and protects the fertile topsoil, thus preventing the silting of rivers and lakes.
