Aeolian processes in hot deserts Flashcards
1
Q
name three wind processes in hot deserts
A
abrasion, deflation, saltation, surface creep, suspension.
2
Q
abrasion
A
process of wind erosion.
concentrated close to the ground surface.
sand particles picked up by the wind an blasted against crop outcrops.
3
Q
deflation
A
process of wind erosion.
removes finer particles and leaving predominantly rocky surface.
4
Q
saltation
A
hopping or bouncing of particles.
0.15mm - 0.25mm in size.
5
Q
surface creep
A
particles pushed or rolled along the ground.
size greater than 0.25mm.
6
Q
suspension
A
particles less than 0.15mm are carried in the air.
eg clay or silt
7
Q
attrition
A
erosion
when particles rub against each other and wear away.
