All about Sand Dunes
Sand dunes are hills of sand shaped by wind. They can move slowly across the land and can be very tall.
Some dunes make a booming sound when sand slides down them.
Wind blows sand up one side of the dune, and it falls down the steeper side, slowly moving the dune forward. Dunes can be very tall, some reaching more than 100 metres high in the world's deserts.
They are often found in deserts, but they can also form along coasts where sand is blown inland.
