Question

Why is the work work of wind more significant in arid and semi arid regions

Answer 1

Wind is more effective at erosion in arid regions because in humid regions smaller particles are held together by the moisture in the soil and by plant roots from the vegetation.

Answer 2

The work of wind is more significant in arid and semi-arid regions because precipitation is less in that area, so the wind is strong.

How the wind is significant?

• In arid and semi-region the vegetation is less wind is more significant
• In this area there is less rainfall
• The rocks in that region change their chemical compound
• The wind is mixed with dust and small particles in that area
• Due to less rainfall the soil becomes dry so small particles are easily transported
• The soil is not bound in that area
