6
Which of these geomorphological processes influence the characteristic desert landscapes?
Transport
Mass movement
Erosion
Weathering
7
In the context of desert aeolian transport, what is surface creep?
Material is removed by strong wind
Larger sand particles slowly roll/slide along the surface
Gravity pulls particles downslope

Permanent river flow
episodic flow: sheet floods, channel flash flooding
sudden downpours
sheet floods, channel flash flooding, past pluvials
10
