A dune is a nature mound of sand formed by the wind, usually along the beach or in a desert or dead tree. Dunes sand form when wind blows sand into a sheltered area behind an obstacle. Dunes grow as grains of sand accumulate. Every dune has a windward side and a slipface. A dunes windward side is the side where the wind is blowing and pushing material up. A dunes slip face is simply the side without wind. A slipface is usually smoother than a dunes windward side. Once it's in motion, sand will continue to move until an obstacle causes it to stop. The heaviest grains settle against the obstacle, and a small ridge or bump forms. Because the obstacle breaks the force of the wind, the lighter grains deposit themselves on the other side of the obstacle. Eventually, the desert, the surface facing the wind crests, sunny and the lighter grains of sand cascade down the other side, or the slip face.

This is how a sand dune may actually move over time it rolls along, maintaining its shape as it goes. How and why does a sand dune crest, As the hot wind moves sand up to the top of the sandpile, the pile becomes so steep it begins to collapse under its own weight, and the sand avalanches down the slip face. The pile stops collapsing when the slip face reaches the right angle of steepness for the dune to remain stable. This angle, which scientists call the angle of repose, sand dune live wallpaper is usually about 30 to 34 degrees.
