Soil Erosion:-

The removal of fertile top soil land by wind or water is called soil erosion. Soil erosion occurs easily in those areas of land which are not covered by vegetation (trees and other plants) or have very little vegetation.

Causes of soil erosion:-

• Soil compaction
• low organic matter
• loss of soil structure
• poor internal drainage
• salinisation
• soil acidity

Types of soil erosion:-

• Sheet and rill erosion
• rill erosion.
• Scalding.
• Gully erosion.
• Tunnel erosion.
• Stream bank erosion.
• Erosion on floodplains.

Answer 2

Answer:

Soil erosion is the removal of topsoil, by the action of wind and water or due to human activities. Topsoil may be carried away by wind or washed away by flowing water due to heavy rains and floods.

Causes of Soil Erosion –

Deforestation- is the cutting down of trees on a large scale may be from forest. This leaves behind loose soil exposed to strong winds, floods, heavy rain and overflowing river orsurface water.

Overgrazing- by cattle without allowing time for the recovery of the grass or shoots on shrubs. This leaves behind loose soil

Poor farming methods- like excessive use of chemical fertilizers results in reduced humus in the soil.
