windward side
A sand dune that got blown away
The slipface of a dune is the steeply sloping side of the dune that faces away from the prevailing wind direction. It forms as sand grains are blown up the windward side and then deposited on the leeward side, creating a steep angle due to gravity pulling the sand grains downward.
The leeward or downwind side is known as the slipface.slipface
When winds blow smaller grains of sand together, they accumulate around a larger grain, forming a small mound. As more sand accumulates, the mound grows into a sand dune. Over time, the dune can continue to grow and change shape as more sand is added and reshaped by the wind.
the top of a sand dune is called the crest of the dune.
A hill of sand in a desert is normally referred to as a dune
A sand dune is a landform, not a climate.
A sand dune is the deposition of windblown sand.
A sand dune is a pile of wind-blown sand.
The wind deposits large loose amounts of sand to create sand dunes. The wind pushes sand up one side. That sand will move over the edge of the dune's top. The sand will pile up up until gravity pulls it down and this creates a steeper slope than the one that faces the wind.
A sand dune is a Constructive force.
