Why is action of wind more prominent in arid and semi arid regions?

Ans The action of wind is more prominent in arid and semi arid areas due to several reasons.

• The wind is dry and light; hence, blows at a greater speed.

• Because of greater speed, it has more velocity to erode and carry away more material.

• Lack of trees in this region means there are less barriers to the flow of winds.

Dry soil is loose and in the absence of vegetation to hold it down it is easily carried away
