hi there
here is your answer:
The removal of soil by running water and wind is known as soil erosion. The soil-forming process and the erosional process of running water and wind are continuous. Generally, there is a balance between these two processes.
The rate of removal of fine particles from the surface is the same as the rate of addition of particles to the soil layer. Sometimes such a balance is disturbed by natural or human factors, leading to a greater rate of removal of soil. When this happens, the entire soil layer may be removed in a few years.
Erosion by Water:
Erosion by water can be of several types, for example, sheet erosion, gully erosion, stream bank erosion, shore erosion and slip erosion.
. Shore Erosion:
The tidal waves dash against coastal rocks, causing them to erode bit by bit
Stream Bank Erosion:
The continuously flowing water erodes the banks of streams and rivers. Gradually the bed of the river widens.
Hilly Region:
Rainfall occurs in torrents and washes away the top layer of the soil. Also, the steep slopes stimulate the eroding power of the rainwater.
Plains:
Here the erosion is comparatively less than on slopes. But in regions where the rivers overflow onto the plains, the erosion is severe. For example, the entire basin of the Kosi River is threatened by the over-flowing of river.
Nature of Rainfall:
Floods and torrential rains cause more damage than light or moderate showers spread over many days.

Types of Soil Erosion:
ADVERTISEMENTS:
Wind and water are powerful agents of soil erosion because of their ability to remove soil and transport it.
(a) Erosion by Water:
Erosion by water can be of several types, for example, sheet erosion, gully erosion, stream bank erosion, shore erosion and slip erosion.
1. Sheet Erosion:
ADVERTISEMENTS:
When a layer of the soil on the surface is removed over a large area by running water, it is called sheet erosion. Sheet erosion is harmful since it removes the finer and more fertile top soil.
2. Rill Erosion:
This is the second stage of sheet erosion. Small finger-like rills begin to appear on the landscape. Over a period of time, the fine rills increase in number and also become deeper and wider. This reduces the actual area under cultivation and the yield of crops decline.
3. Gully Erosion:
ADVERTISEMENTS:
When soil is removed by water flowing along definite paths downs the slope or in channels, it is called gully erosion. Gullies cut up agricultural land and make it unfit for cultivation. Badland is a region with a large number of deep gullies or ravines, e.g., Chambal Valley in Madhya Pradesh.
4. Stream Bank Erosion:
The continuously flowing water erodes the banks of streams and rivers. Gradually the bed of the river widens.
