Answer 2

Explanation:

5.forests help in soil conservation in a way that their roots hold the soil firmly , hence preventing soil erosion , more the trees , more the roots will be holding the soil .(keeping it simple)

4.Graduated terrace steps are commonly used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice.

why is it a good measure to stop soil erosion :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.
