Mention any two human activities which are responsible for the process of soil erosion. Explain the two types of soil erosion.
Human activities responsible for the process of soil erosion are:
- Deforestation, over-grazing.
- Defective methods of farming.
Types of soil erosion:
- Sheet erosion — Sometimes, water flows as a sheet over large areas down a slope and removes the top soil.
- Gully erosion — Running water cuts through the clayey soils and makes deep channels called gullies. The land dissected by gullies become unfit for cultivation and is known as bad land.
