<h2>The correct answer is: Deflation.</h2>

Explanation:

  • In geology, Deflation can be defined as the process by which loose, light weight and small particles formed by the weathering of rocks, erosion of top-soil of the earth crust or the dust and sand particles are carried from one place to another by the action of wind.
  • When these particles hit or strike an obstruction like a mountain or hill they fall down on the ground.
  • Gradually with time, numerous such particles fall down and accumulate on the ground after striking an obstruction and eventually result in the formation of a sand dune.
