Wind Erosion and Deposition

For sand dunes to form there must be an abundant supply of sand and steady winds A strong wind slows down often over some type of obstacle such as a rock or some vegetation and drops its sand As the wind moves up and over the obstacle it increases in speed It carries the sand grains up the gently sloping upwind side of the dune by saltation
