what is soil erosion
Answers
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.
Answer:
soil erosion :-
>> Natural events like wind , rain and flood carry away the topsoil with them, from one place to another. This process is called soil erosion. Soil erosion is likely to occur when no plants are rooted in the soil as roots of plants hold soil particles together. When the fertile topsoil is eroded, the less fertile subsoil comes to the surface which leads to a fall in crop production.
Gradually, the land loses its fertility and becomes barren.
