Dunes

Dunes are mounds or ridges of loose sand shaped by the wind, commonly found in deserts and along beaches. They form when wind transports and deposits sand particles, accumulating around obstacles or in areas where the airflow slows. The size and shape of dunes depend on factors like wind strength, sand availability, and the landscape. Dunes can shift and change over time, creating dynamic features in the environment. They are important for ecosystem habitats, influence local climate, and serve as natural indicators of wind patterns and geomorphic processes.
