Wind and waves form sand dunes on the beach
Sand hills form in areas where wind can easily transport and deposit sand, such as deserts, beaches, and coastal regions. They can also form in places where sand dunes have been stabilized by vegetation.
Sand dunes are shaped by the wind in both deserts and beaches. The wind blows grains of sand, causing them to accumulate and form dunes that can vary in size and shape depending on the strength and direction of the wind.
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.
Both deserts and beaches have sand that is sometimes blown into dunes.
Quartz is the tough mineral most likely to survive extensive chemical weathering and form sand grains on beaches or dunes. Its hardness and resistance to chemical weathering make it a common component of sand in these environments.
Places with sand like beaches or sand dunes
Sand dunes can form in some areas of the desert, along the coast or near major bodies of water such as the Great Lakes. Some form in areas that were laid bare by the retreat of glaciers after the last ice age.

Sand dunes can be found in deserts, beaches, and anywhere else sand is present.
Huge piles of sand are called sand dunes. Sand dunes typically form in deserts or coastal areas where there are strong winds that shape and move the sand into these large structures.
The massive wind blown piles of sand are called sand dunes. This is when sands blow into a pile.
