Answer 1

Answer:

The correct answer to the question is :-

(a) Both A and R are true, and R is the correct explanation

Explanation:

Shelter belts are strips of trees and or shrubs planted to protect fields, homes cannels or other areas from wind and blowing soil or sand.

The soil erosion caused due to wind is called wind erosion and shelter belts help prevent erosion as :-

• The roots of the strips of trees hold the soil together and prevent it from eroding due to water or other such agents.
• Shelter belts are vegetative barriers that are designed to reduce wind speed. This also prevents wind erosion (soil erosion due to wind)
