Question

Three reason for soil erosion

Answer 1

$\huge{\color{purple}{\underline{\mathfrak{Answer:}}}}$

The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away.

Answer 2

Answer:

The top layer of soil is very light which is easily carried away by wind and water. The removal of topsoil by the natural forces is known as soil erosion.

Explanation:

Three reasons for soil erosion are stated as follows:

1. When strong winds blow, the topsoil along with the organic matter is carried away by the wind. This can happen more in the areas where the number of trees and plants is less.

2. When rain falls on unprotected topsoil, rain water washes it down into the streams and rivers.

3. Human activities such as expansion of urban areas have led to the removal of vegetation from many regions. The bare land, thus, has been exposed to external agencies (winds or rains) for the soil erosion.
