Wind transports sand grains primarily through two processes: saltation and suspension. In saltation, sand grains are lifted off the ground and then fall back, bouncing along the surface, while in suspension, lighter particles are carried high into the air by the wind. This transport can lead to the formation of various landforms, such as dunes, as the wind deposits the sand in different locations. The effectiveness of wind in moving sand depends on factors like wind speed and grain size.
Small grains erode faster than big grains because small grains have a larger surface area relative to their volume, allowing more contact with flowing water or wind that can wear them away more quickly. Additionally, small grains are often lighter and more easily transported by wind or water, further contributing to their erosion.
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.
You can separate sand grains from salt grains by combining the mixture with water to dissolve the salt. The sand will settle at the bottom of the container, allowing you to pour off the salt solution. The sand can then be dried and collected.

The wind carrying sand grains deposits the sand when the wind's velocity decreases, or when an obstacle interrupts the wind flow. This causes the heavier sand grains to settle and accumulate, forming sand dunes.
Wind carrying sand grains deposits the sand when the wind slows down or hits an obstacle.

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.
A deposit of wind-blown sand is called a sand dune. Sand dunes form in deserts, beaches, and other areas where wind is able to transport and deposit sand grains.
This type of wind erosion is called abrasion. It occurs when sand grains carried by the wind hit and scrape against rocks, wearing them down and creating a polished surface.
Wind erosion can cause the formation of dunes. As wind carries sand particles, they collide with each other and with the ground, eventually depositing the sand in mounds known as dunes. This process is common in arid and coastal regions.
Sand blown loose from dry desert soil often builds up into dunes. A dune may begin to form when windblown sand is deposited in the sheltered area behind an obsticle, such as more grains accumulate. Dunes are gradually moved along by wind.
The wind picks up grains of sand and it is the sand that weathers the rocks, often creating weird shapes.
