Question

name two agents of soil erosion

for each agent you have named, mention the region where this agent carries out soil erosion ​

Answer 1

Answer:

Soil erosion is the displacement of the upper layer of soil, it is one form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans. In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion.[1] Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks.Soil erosion could also cause sinkholes.

Answer 2

Soil

The soil is the top layer of the earth’s surface. It is made up of dirt and rock. It is filled with air and life. A variety of organisms, like insects, earthworm, live in soil. For plants, soil serves as a storehouse of water and minerals needed for their growth. It also provides shelter to many animals that live on or in the soil. Without soil, there would be no grass, no crops, no trees, no food for us and other animals.

Soil Erosion

It is a process in which the top fertile layer of soil is lost. Due to soil erosion, the soil becomes less fertile. 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.

Causes of Soil Erosion

Various agents, like wind, water, deforestation, overgrazing by cattle, etc., cause soil erosion.

Agents of Soil Erosion.

Water: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. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion..

Gravity:Gravity is responsible for erosion by flowing water and glaciers. That's because gravity pulls water and ice downhill. These are ways gravity causes erosion indirectly. ... Gravity can pull soil, mud, and rocks down cliffs and hillside.

Precise Answer is given.
