SOIL EROSION
Soil erosion is defined as the wearing away of topsoil. Topsoil is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. One of the main causes of soil erosion is water erosion, which is the loss of topsoil due to water.
CAUSES OF SOIL EROSION
1. water run off and rainfall intensity
2. slope f the land
3. deforestation
4. soil texture
5. wind
6.land tillage
7. over grazing
8. harsh climatic conditions
9. erodibility of soil
10. other human activities like quarrying and mining

Soil erosion is a natural process which occur when there is loss of or removal of top layer of soil to due to rain, wind, deforestation or any other human activity.
Causes:
1. Soil Texture:
Small grain and open structure soil erodes more than the larger grain and closed structure soil.
2. Ground Slope:
Steeper slope ground erodes more than the ground having mild slope due to increased speed of run off than infiltration.
3. Intensity and amount of rainfall:
More the intensity of rainfall more will be the soil erosion.
4. Mismanaged utilization of soil resources:
The soil erosion is enhanced by improper surface drainage, removal of forest litter, overgrazing etc.
5. Distribution of rainfall and landscape:
If the ground surface is such that rainfall distributes evenly, there is not plenty rainfall, the erosion will be less.
6. Deforestation:
It is one of the major factors responsible for Soil erosion. Removal of forest cover which function as a binder of the top layer of the soil with increasing land demand have resulted in enhancing extent of soil erosion.
