Description: Aeolian dunes are hills or ridges of sand formed by the wind in desert or coastal environments. The shape and size of aeolian dunes are influenced by wind direction, sand supply, and vegetation. These dunes are significant in the study of sedimentary processes and desert geomorphology, as well as in understanding past climatic conditions.
