rock pedestals
Wind sculpts stratified rock into pedestals by wind abrasion and weathering, e.g. Gava Mountains, Saudi Arabia
A ridge and furrow landscape. Wind abrasion concentrates on weak strata; leaving harder material upstanding. The Sphinx at Giza may be a modified yardang! - See more at: http://www.revisionworld.com/a2-level-level-revision/geography/arid-and-semi-arid-environments-0/features-produced-wind-erosion#sthash.BIB1z0JR.dpuf

vInselbergs
Wind (and water) attacks the original surface leaving round-topped inselbergs (through exhumation). The material removed has a deep-seated ‘decay’ origin and may display extensive ‘unloading’ (subsurface weathering). There are two major forms: domed inselbergs (bornhardts) and boulder inselbergs (Kopjes, rubbins), e.g. Matopos, Zimbabwe
Bornhardt Formation

Deflation hollows
These are caused by the removal of fine particles by the wind, lowering the surface and creating a hollow, the best known example is the Qattara Depression - See more at: http://www.revisionworld.com/a2-level-level-revision/geography/arid-and-semi-arid-environments-0/features-produced-wind-erosion#sthash.BIB1z0JR.dpuf
In aeolian processes, wind transports and deposits particles of sediment. Aeolian features form in areas where wind is the primary source of erosion. The particles deposited are of sand, silt and clay size. The particles are entrained in by one of four processes. Creep occurs when a particle rolls or slides across the surface. Lift occurs when a particle rises off the surface due to the
