Question

What is soil erosion ?

Answer 1

Soil erosion is defined as the wearing away of topsoil. Topsoil is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. Therefore, this is the layer that farmers want to protect for growing their crops and ranchers want to protect for growing grasses for their cattle to graze on.

Soil erosion is the process of wearing away of the surface layer, or top soil, by the transportation of the surface particles under the mechanical actions of agents like wind, river, or even glacier.
While soil erosion removes the topsoil causing loss of fertility of soil at one place while leading to the emergence of new soil at another.

Also, any erosional event is accompanied by a depositional event, thereby eroded fertile soil forms fertile deposits like delta or Aeolian plains
