The role of wind: erosion (deflation and abrasion), transportation (suspension, saltation, surface creep), deposition
Wind erodes, moves, and drops sediment in hot deserts. It does this through several distinct processes, each shifting material in a different way.
Real World
The Qattara Depression in Egypt, 134 metres below sea level, was largely carved by wind deflation removing loose sediment over millennia, while nearby ventifacts in the Western Desert show faceted surfaces abraded by sand-laden winds.
Exam Focus
Always state particle size when explaining transport mode — suspension carries clay/silt, saltation moves sand, surface creep shifts pebbles.
