Sand dunes are found in many deserts, as well as in some less arid areas of the world.
Sand dunes can be found in the deserts. The Sahara Desert is known for being the largest hot desert in the world and known to have sand dunes. Other places includes the Middle East and especially Saudi Arabia.
Genericall such hills of sand are called "dunes". They are also found in deserts.
Sand dunes on the beach are important and used for protecting the land against potential ravages by storm waves from the sea. The largest complex of dunes are found inland in dry regions associated with ancient lakes.

Wind forms sand dunes by picking up dry sediments and accumulating them over time to create over time.

A xerosere is a succession of ecological communities which originated in a dry habitat such as a sand desert or sand dunes.
Sand dunes need at least 3 ingredients - lots of sand, lots of wind, and minimum rain. Lots of sand is found along the former edges of the ice sheets, where it was deposited when the glaciers finished grinding down the rocks and melted in the warming climates. Dry is found on the eastern side (lee) of coastal mountains which strip off the ocean's moisture. Wind is everywhere.
Sand blown loose from dry desert soil often builds up into dunes. A dune may begin to form when windblown sand is deposited in the sheltered area behind an obsticle, such as more grains accumulate. Dunes are gradually moved along by wind.
Desert regions are typically characterized by arid conditions and a scarcity of vegetation, with sand dunes, rocky plateaus, and barren landscapes being common physical landforms found in very dry areas.
