Answer 2

Question :

How can soil erosion be reduced ?

Answer :

→ Soil erosion can be reduced in the following ways :-

Afforestation : The best way to reduce or prevent soil erosion is by planting trees in large number. The roots of trees hold the soil together.

Construction of dams : It is used to control floods.

Terrace farming : It is an effective way to minimise soil erosion in hilly areas, it is done by making steps on hill slopes.

Question :

What are the factors for soil erosion ?

Answer :

→ The factors responsible for soil erosion are as follows :-

Deforestation : Cutting of trees in large number is the main cause of soil erosion.

Floods : Floodwater washes away the topsoil and thus causes soil erosion.

Forest fires : It burns the plant cover and expose the soil to the agent like wind and water which causes soil erosion.

Overgrazing : Grazing of animals on the same piece of land year after year is also a reason for soil erosion.
