sand dunes

Windswept coastal hills

Sand dunes are hills or ridges of sand shaped by wind, found in deserts and along coastlines.

They form when wind deposits sand against obstacles, building mounds that can grow massive over time.

Dunes migrate slowly as wind moves sand from one side to the other: The sand dunes stretched for miles across the desert.

Coastal dunes often anchor fragile ecosystems.
