Answer 2

Soil erosion is the removal of the top layer of soil. Soil erosion occurs due to heavy rainfall and floods. Soil erosion can be prevented through afforestation because it is a process of planting new trees. The establishment of a forest in an area where there were no trees previously is called afforestation. Trees help prevent soil erosion by strengthening the soil.

Steps to prevent soil erosion:

1. Planting more trees as roots of trees and plants holds the soil and does not allow the soil to wither off.
