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.

What is an aeolianite?

What Controls the Shape and Motion of Sand Dunes?
When wind carrying sand slows down or is trapped by some obstacle, such as a boulder or plant, the sand gets deposited. As the sand accumulates, a sand dune can form. Dunes often form on beaches or in deserts. Sand dunes move over time as, little by little, sand grains get moved by the wind from one side of the dune to the other.
How are dunes and deltas different?

What land feature would probably form if sand was deposited by wind?
A sand dune would form if sand was deposited by wind. Sand dunes are mounds of sand shaped by wind patterns and are commonly found in deserts or coastal areas with strong winds.
How do sand dunes form Why is one side of a dune different than the other one?
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.
What is the top of a sand dune called?
the top of a sand dune is called the crest of the dune.
What would you expect to happen to the position of the sand dune with the passage of time?
The position of a sand dune is never static, it is always changing in form, mass and position.
