Question

Write a short note on Conditions necessary for work of wind.

Answer 1

The wind is a significant agent of erosion in the deserts. The following conditions are necessary for the wind to become effective:

1. Arid areas are essential. In such areas, the rate of evaporation is greater than the rate of precipitation. Due to dryness the soil becomes loose and is carried by the wind.
2. Sparse vegetation cover or absence of trees, so that there is no obstacle for wind.
3. Presence of dry loose materials at the surface which carries out erosion.
4. A wind velocity high enough to pick up and move sediments.
