Soil Erosion
Soil of Class 7
The denudation of soil cover and subsequent washing down is described as soil erosion.
Causes of Soil Erosion:
- Human activities like deforestation, over-grazing, construction and mining.
- Defective methods of farming.
- Ploughing in a wrong like up and down the slope forms channels makes way for quick flow of water. This leads to soil erosion. way etc. disturb this balance. Natural forces like wind, glacier and water lead to soil erosion.
- Sometimes water flows as a sheet over large areas down a slope. In such cases the top soil is washed away. This is known as sheet erosion.
- Wind blows loose soil off flat or sloping land known as wind erosion.
Effects:
- Makes land unsuitable for cultivation.
- Land so developed is called bad lands, in the Chambal basin they are known as ravines.
