Question
How does wind perform its task in desert areas? Is it the only agent responsible for the erosional features in the deserts ?
Solution
1. Winds move along the desert floors with great speed and the obstructions in their path create turbulence. Storm winds are formed which are very destructive.
2. Winds cause deflation, abrasion and impact. Deflation includes lifting and removal of dust and smaller particles from the surface of the rocks from the surface of the rocks.
3. The impact is the simply the sheer force of momentum which occurs when sand is blown into or against a rock surface.
4. Winds are not the only agent responsible for the erosional features of the deserts. Along with the winds, the running water is also important for this.
These are the ways in which wind action creates a number of interesting erosional and depositional features in the deserts.
