A sand dune is a large sand hill formed by different wind patterns blowing over an area for an extended period of time. Over time, the wind shifts and moves the sand over itself, until it creates a large dune.
No! An ocean is a large body of water. A sand dune is a large pile of sand that moves when driven by the wind. Dunes may be found on some beaches near oceans, however.
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 top of a sand dune is called the crest of the dune.
