What is soil erosion Class 2?
It is a process in which the top fertile layer of soil is lost. Due to soil erosion, the soil becomes less fertile. The top layer of soil is very light which is easily carried away by wind and water. The removal of topsoil by the natural forces is known as soil erosion.
What is soil erosion explanation for kids?
Soil erosion is the washing or blowing away (by water or wind) of the top layer of soil (dirt). This is a serious problem for farmers. If the soil has eroded, the crops that make food will not grow very well.
What is soil erosion 2 marks answer?
Soil erosion means destruction of top fine layer of soil. winds and water are the most powerful agents of soil erosion. water erosion is more serious which takes place in the form of gully erosion and sheet erosion. wind erosion occurs mainly in arid and semi arid regions.

What are the key points of soil erosion?
Key Points Of Soil Erosion It is the natural process of wearing away of the topsoil, but human activities have accelerated the process. It is usually caused due to the removal of vegetation, or any activity that renders the ground dry. Farming, grazing, mining, construction and recreational activities are some of the causes of soil erosion.
What are the different soil erosion types?
The different soil erosion types are explained below. The erosion due to the impact of falling raindrops on soil surface leading to the destruction of the crumb structure is known as the raindrop or splash erosion. It is the uniform removal of soil in thin layers from the land surface caused by the wind.
How to prevent soil erosion on slopes?
Mulch matting can be used to reduce erosion on the slopes. Put a series of fibre logs to prevent any water or soil from washing away. A wall at the base of the slope can help in preventing the soil from eroding.
