Explain types of soil erosion mostly observed in india by running water.Mention human activities responsible for soil erosion and deposition resulting in a disaster?
Answers
Answer:
Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
Explanation:
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.
The running water cuts through the clayey soil and makes deep channels as gullies.In the chambal region bad lands are called Ravines.
Sometimes water flows over large areas down a slope.In such a case the top soil is washed away.This is known as Sheet erosion.
Human activities responsible for this:
Contour ploughing
Over grazing
Construction
Mining....etc.
