On a hard smooth surface sand can act almost like thousands of tiny ball bearings.
However when used on ice and snow sand improves traction, preventing slipping and works when it is too cold for salt to melt the ice and snow.
The upwind direction of a sand dune has a gentle slope. A steep slope is on the downwind side. The pronounced slope of a sand dune is called a slip face. Sand erodes from the wind off the slip face. To learn more about sand dunes, visit http://www.tulane.edu/~sanelson/geol111/deserts.htm.

role in formation of sand dunes (in sand dune: Formation and growth of dunes)...sand brought up the windward slope. When this depositional slope is steepened to the angle of repose of dry sand (about 32°), this angle is maintained and the added sand slips down the slope or slip face. When this happens, the dune form is in equilibrium, and the dune moves forward as a whole, sand being eroded from the windward side and deposited on the lee.
The side of a sand dune facing the ocean is called leeward.
The slip face of a dune is the steep, leeward side that forms as wind-blown sand accumulates on the windward side, creating a slope that eventually becomes unstable. As sand grains are transported over the crest by the wind, they tumble down the slip face, which can have a more gradual incline compared to the steep angle of the windward side. This process continues as the dune migrates over time, reshaping its structure. The angle of the slip face is typically around 30 to 34 degrees, which is known as the angle of repose for sand.
The leeward side of a dune is shorter and called the slip face. Dunes often serve an important purpose in protecting land from storm waves.
Both sand and fog slip away from a person's hand....which is what happened to the house in this movie. It didn't belong to anyone in the end.
The steep side of a dune is called the slip face. It is the side of the dune where sand grains are deposited as they slide down due to gravity.
The water molecules are far smaller than the spaces between the sand grains and can easily slip through, gravity pulls the water down.
The steep face of a sand dune is called the slip face or the lee side. It is typically located on the leeward side of the dune where the wind direction forces the sand to accumulate in a steep slope. This portion of the dune is constantly shifting and changing due to the interaction of wind and sand movement.
The steepest side of a dune is known as the "slip face." This side forms as wind blows sand over the crest of the dune, causing it to accumulate on the leeward side. The angle of the slip face typically ranges between 30 to 34 degrees, depending on the type of sand and moisture content. This steep slope is a result of gravity and the angle at which the sand can remain stable.
