What are drifts of snow?

What does a snow drift look like?

Snow drifts are massive deposits of snow created by wind that shapes them into a mound. They can resemble sand dunes and are moulded in much the same way as stormy winds push round the snow. Light snow is whipped up by the gusts and pushed against objects like walls and cars.

What causes sand dunes to drift?

Sand dunes move via a few different means, all of them helped along by wind. One way that dunes can move is by saltation, where sand particles skip along the ground like a bouncing ball. When these skipping particles land, they may knock into other particles and cause them to move as well, in a process known as creep.

Why do sand dunes keep changing their position?

Abstract: Sand can create an endlessly moving collection of dunes, drifted by the prevailing winds. However, it can happen that, changing the winds, also the motion and the shape of the dunes change. Moreover, in the case that wind is blowing from a prevailing direction, the dunes migrate.
