Answers
missing of topper most layer of soil is called soil erosion
types: *wind erision
* water erosion
* gravity erosion
Answer:
Soil erosion is the removal of soil by the forces of nature like wind and water, more rapidly than the various soil forming processes can replace it.”
Types of Soil Erosion :
(a) Water Erosion : Water is a powerful agent of soil erosion. Following are the major types of erosion caused by water.
(i) Sheet Erosion : When the top layer of the soil is removed over a large area by the running water, it is called as sheet erosion.
(ii) Gully Erosion : This is the third stage of sheet erosion. With further erosion of the soil, the rills may deepen and become enlarged, and are ultimately turned into gullies. The main cause of gully erosion is the removal of vegetation, particularly of trees with their widespread binding roots. Gullies cut up agricultural land and the entire area may be turned into a bad land
topography. Gully erosion is also responsible for the formation of ravines.
(b) Wind erosion : Wind is a powerful agent of erosion in arid and semi-arid lands with little rainfall. Wind can lift the valuable top soil from one area and deposits in another area.
