Q. Consider the following processes regarding wind erosion:

1. Deflation refers to the removal of loose particles from the surface of rocks.
2. Abrasion is the frictional movement of sand particles within themselves.
3. Attrition involves the scraping of particles from the rock surface.

Which of the above are explained correctly?
Answer: Only 2 and 3
Notes: Only statement 1 is correct. Deflation is the removal of loose particles from rock surfaces by wind. Abrasion involves rock surfaces being worn away by particles carried by the wind, not particles moving within themselves. Attrition is the breakdown of particles due to collision with one another, not scraping of rock surfaces. Thus, 2 and 3 are incorrectly explained.
