Question

Difference between sand dunes and sandy features in topography

Answer 1

Mounds of loose sand grains that are piled up by wind movement are referred to as sand dunes. There are many sand dunes located within the deserts of the Southwestern United States. You can also see sand dunes along beaches where sand blows inland and creates a dune that separates the water from the habitat. In the Sahara Desert of Africa, the sand dunes are so large they are referred to as sand seas. The sand dunes move with the wind and resemble a moving sea.
