  • D.Preventing gullies and hence further soil loss.

Answer: A

Shelter belts help in checking wind movement to protect soil cover.

Shelter belts are rows of trees planted to break the force of the wind. They are used in dry and coastal areas, such as western India, to check wind erosion and the movement of sand dunes and so protect the soil cover.

Slowing water flow and preventing gullies are the work of other measures, such as contour ploughing, terracing, check dams and contour barriers. Mulching is the usual method for retaining soil moisture.
