Document Summary

In other words, in arid and semi-arid regions and along coastal beaches. Aeolian erosion: two fundamental categories: deflation and abrasion (1) deflation is the movement of loose particles by wind. Ventifact: not all deserts are warm aeolian processes occur in arid polar settings as well. >(cid:883) mm rolling (cid:498)creep(cid:499) coarse sand traction is transport along ground by rolling or sliding: wind erosion. 0. 1 (cid:883) mm saltation (cid:498)jumping(cid:499) sand. 0. 001 (cid:882). (cid:883) mm suspension (cid:498)dust storm(cid:499) clay & silt: occurs when wind velocity drops, when particles amass, or when. Loess: wind deposited silt that has settled out over time, lacks visible layering, large deposits in north america and eurasia are a result of glacio-fluvial sediments during late-cenozoic era that were transported by off-glacier by strong katabatic winds. Coastal processes: action of waves is a major force along the land-water interface (coast, erosion, transport and deposition operated in this setting as well.
