Question

What effect does planting trees and bushes on a steep hill have?

Answer 1

Answer:

D- It helps stop erosion.

Explanation:

Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.

The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.

Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion. Other factors that affect the rate of erosion in an area include the following; farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.

In order to mitigate or stop the rate of erosion in an environment, trees and bushes should be planted on a steep hill because they will obstruct the free flow of water, as well as absorbing it.
