Soil Erosion


Hi Friends

Good Morning!!!

What are things needed to grow plants?
Oxygen, water, manure, soil etc.

Let us learn about Soil Erosion.

Soil is formed as a result of weathering of rocks. There are also many living organisms in the soil. Soil is, in fact a product of the interaction of living organisms with rocks. Soil has many layers. The topmost layer is called the topsoil and is the most fertile. The removal of this topsoil is called soil erosion.

Causes of Erosion

The main cause of soil erosion is the removal of vegetation. Vegetation removal takes place due to removal of forest covers. Unscientific farming has also led to barren lands.

The removal of vegetation exposes the topsoil to water and wind. Water and wind cause the topsoil to be removed.
