- Soil erosion refers to the removal of soil at a greater rate than its replacement by natural agencies. Topography, rainfall, wind, lack of vegetation cover, land use practices, etc. are the causes of soil erosion.
- Water erosion means that soil particles are detached either by splash erosion (caused by raindrops), or by the effect of running water. It is mainly categorized into the following types:
- Sheet Erosion - This means when a fairly uniform layer of soil is removed over an entire surface area.
- Rill Erosion - It occurs where water runs in very small channels over the soil surface, with the abrading effect of transported soil particles causing incision of the channels into the soil surface.
- Gully Erosion - It occurs when rills flow together to make larger streams (gully formation).
- Bank Erosion - It is caused by water cutting into the banks of streams and rivers. It can cause large floods and major destruction to property.
- Hence, option (c) is the correct answer.

Sheet Erosion
Sheet erosion is a type of erosion where a fairly uniform layer of soil is removed over an entire surface area. This process can occur due to factors such as rainfall, wind, or human activities.
Causes of Sheet Erosion
- Rainfall: Heavy rainfall can cause the top layer of soil to be washed away, leading to sheet erosion.
- Wind: Strong winds can blow away the topsoil, causing erosion to occur uniformly across the surface.
- Human Activities: Activities such as overgrazing, deforestation, and improper agricultural practices can also contribute to sheet erosion.
Effects of Sheet Erosion
- Loss of Fertile Soil: Sheet erosion can result in the loss of fertile topsoil, which is essential for plant growth.
- Reduced Soil Quality: As the top layer of soil is eroded, the quality of the remaining soil is diminished.
- Environmental Degradation: Sheet erosion can lead to environmental degradation, affecting ecosystems and water quality.
Prevention of Sheet Erosion
- Conservation Tillage: Practices such as no-till farming help to reduce soil disturbance and prevent erosion.
- Cover Crops: Planting cover crops can help protect the soil from erosion by providing ground cover.
- Contour Farming: Farming along the contour of the land can help prevent water runoff and soil erosion.
In conclusion, sheet erosion is a significant issue that can lead to the loss of soil fertility and environmental degradation. It is essential to implement measures to prevent and mitigate the effects of sheet erosion for sustainable land management.
