Here's how it works:
* Wind Erosion: Wind picks up loose sediment (sand, silt, or clay) and carries it away.
* Deposition: When the wind slows down or encounters an obstacle, it loses energy and deposits the sediment.
* Dune Formation: Over time, the deposited sediment accumulates and forms mounds or ridges called dunes.
There are different types of dunes, each shaped by the wind's direction and strength.
