Question
Vegetation plays a big role in stabilizing slopes.

Answer

Vegetation plays a big role in stabilizing slopes because-
  1. The strong root system of trees and other plants help to hold the soil in place.
  2. When these trees are removed, the soil becomes loose and can be easily washed away.
  3. This is why, when there is dense forest cover there is stabilization of slopes but deforested areas are likely to be sites of mass wasting.
