Causes of Soil Erosion :
1. Steep slopes: Steep slopes increase the rapidity and intensity of soil erosion.
2. Torrential rainfall: Heavy rainfall forms gullies and ravines leading to a bad land topography.
3. Strong winds: Winds, through the process of deflation, blow away layers of fine soil.
4. Overgrazing: Over cropping and shifting cultivation renders the soil infertile.
5. Deforestation: Deforestation exposes the area to soil erosion. Reckless cutting of trees has resulted in soil erosion by chos of the Shiwaliks.
