Aeolian Environment Flashcards
Less capable of picking up and transporting coarse materials but can spread sediment over large area as well as high into the atmosphere
Air transport
Capable of picking up and transporting coarse material
Water transport
Windblown sands are moved by skipping and bouncing along the surface
Saltation
Saltating grains collide mid air, before reaching the bed
Sheet flow
Larger, heavier grains are transported while still in contact with the ground
Traction
The process whereby traction load maintain grain to grain collision
Creep
Grinding action, while on transit wind borne particles often collides with one another
Attrition
May aid shaping of some of the detail of major form
Wind abrasion
Lifting and removal of loose, grained materials from earths surface
Deflation
Consist of finer particles suspended in the air
Suspended load
used as paleocurrent indicator
with still pointed crest
wind or sand ripples
mounds and ridges of sand fro wind’s bed load
dunes
solitary crescent shaped dunes
barchan
long ridges seperated by troughss and oriented at right angle to the prevailing wind
transverse
between barchan and transverse dunes
barchanoid
