Wind abrades rock by sandblasting, this is the process in which wind causes the blowing of millions of grains of sand, which bump across the surface of rocks.
Sand is not a compound and haven't a molar mass; also different types of sand exist.

Fine-grained sand generally erodes fasterthan coarse-grained sand.
The contracting and expanding of rock from the sun or water and ice breaks any rock that has a weak seam. The wind tends to grind rocks down by blowing sand grains against the rock's surface.
Wind carrying sand grains deposits the sand when the wind slows down or hits an obstacle.

Dunes are typically formed by wind erosion, specifically through a process called aeolian erosion. This occurs when wind transports and deposits sand grains, shaping them into dunes over time.
The wind can pick-up and carry sand grains. It is these sand grains that act as 'sand-paper' against the rocks, eroding the rocks into weird shapes.
Wind erosion of rocks create sand grains. The wind blows these grains along until some of the grains gather in a sheltered spot. It is here that the accumulating sand grains begin to form the dunes. As more sand is blown up the dune and over the crest, so the dune appears to be slowly moving forward, down wind. It is why these fresh sand dunes are known a mobile dunes.
abrasion
The wind picks up grains of sand and it is the sand that weathers the rocks, often creating weird shapes.
Grains of sand will move faster compared to pebbles. Sand is lighter and will easily get carried by wind, unlike pebbles, which are heavier in comparison.

Sand grains or smaller.
Dunes are hills or small mountains made of sand and normally form in the desert. They can move because the wind may blow the sand from one point to another.
