In the desert
When wind drops its load of sand, it can form a hill called a sand dune. Sand dunes are commonly found in deserts and coastal areas, and their formation is a result of the movement and deposition of sand by wind.
Scientificly, sand dunes were formed by chemical weathering.

An aeolianite is a form of rock formed from dune sand.
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.
the top of a sand dune is called the crest of the dune.
The position of a sand dune is never static, it is always changing in form, mass and position.
A hill of sand in a desert is normally referred to as a dune
A sand dune is a landform, not a climate.
The formation of a sand dune can take hundreds to thousands of years, depending on factors such as wind patterns, sediment supply, and vegetation cover. The process begins with sand accumulation and then gradual migration and shaping by wind processes such as saltation and erosion.
A sand dune is the deposition of windblown sand.
