State any two reasons for soil erosion
Answers
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.
2 reasons could be wind storms and river flood or water body lead erosions of top layer soil
