| Deserts | |
| Streamlined flow | |
| Turbulent flow | |
| Vorticose Flow | |
| Wind-velocity profile | |
| Boundary layer | |
| Bernoulli effect | |
| Deflation | |
| Abrasion | |
| Sedimentation | |
| Accretion | |
| Encroachment | |
| regions with very low annual rainfall (less than 300mm, 11in), sparse vegetation, extensive areas of bare rock, and alluvial plains | |
| parallel layers of moving air | |
| irregular movement of air, up and down and side to side | |
| spiral flows around a central axis | |
| graph of varying wind speeds from the ground to some altitude | |
| lower 1000m (3280ft) of atmosphere affected by frictional drag from ground surface | |
| when fluids flow, they create a pressure gradient where high pressure is concentrated near the ground and low pressure sits above it | |
| the removal of loose particles by the wind | |
| particles being transported by the wind wears away at a surface | |
| grains fall out of the air or stop creeping forward | |
| grains being moved by saltation hit the surface with a strong enough force to stop movement where they strike | |
| deposition that occurs on a rough surface, some obstruction prevents creep from moving particles forward |
