Answer 2

The soil is the top layer of surface of the earth. Soil Erosion is the removal of the layer of the soil.

Explanation:

Reasons Behind Soil Erosion:

• Wind:  At the point, when solid winds blow, the topsoil alongside the organic matter is moved by the wind. This happens all the more frequently when the land isn't covered with grass or plants. Such conditions are exceptionally normal in desert and semi-desert locales where solid winds blow much of the time.

• Water:  At the point when it downpours in the sloping regions, the soil moves washed away towards the fields. The running water stores the mineral-rich soil in the riverbed and throughout the long term this statement of soil can shift the direction of the waterway. This can prompt floods which cause the annihilation of life and property.

• Overgrazing:  At the point when dairy cattle are permitted to nibble on a similar field over and again, all the accessible grass, including the roots are eaten by them. This makes the topsoil helpless against wind and streaming water, prompting soil erosion.  

•  Deforestation:  Chopping down of trees for a large scale by human is deforestation. The roots of trees hold the soil together, hence keeping the soil from getting uprooted. At the point when large areas of forests are cleared, the topsoil gets removed by wind and flowing water.
