Question

How does terrace farming help to prevent soil erosion?

Answer 1

Soil erosion occurs when the water with high velocity runs down washing the soil. As many terrace or step like slopes are present in terrace farming it reduces the speed as well as the quantity of water moving over the soil surface as a result of which it checks soil erosion by preventing it.

Answer 2

Explanation:

Terrace Farming reduces the speed of the water since it forms steps like structure, this gives a break in the flow of water (as like a resistor in the circuit offers break).

The more slower the water flows the less soil erosion happens
