The denudation of the soil cover and subsequent washing down of soil
Causes of Soil Erosion
Natural forces - Wind, glacier water
Human factors - deforestation, over grazing, construction, mining etc.
Defective methods of farming, Ploughing in a wrong way
Types of Soil Erosion
Gully Erosion: The running water cuts through the clayey soils and makes deep channels called gullies
Sheet erosion: When water flows as a sheet over large areas down a slope. Top soil washed away.
Bad Lands: When land become unfit for cultivation eg- ravines.
Wind Erosion: Wind blows loose soil off flat or sloping land.
Contour Ploughing: Ploughing along the contour lines can decelerate the flow of water down the slopes.
Terrace Cultivation: Steps can be cut on the slopes making terraces, it restricts soil erosion,
Strip Cropping: Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind.
Shelter Belts: Planting lines of trees to create shelter. They have helped to stabilize sand dunes.
