Gully and sheet erosion differnce |
|
Answer» 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. 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. |
