•Wind picks up tiny,
loose particles (e.g. sand).
•Removal of these
particles, leaving only larger gravel and
pebbles can lead to “desert pavement.”
•Constant sand blasting
of rocks causes a flattened and pitted
windward surface.
•Blowing sand comes to rest behind obstacles and eventually becomes a sand
dune.
•On a dune’s surface
sand rolls and slides producing sand ripples.
