question
Wind erosion can cause __________, which can create shallow depressions called __________.
answer
deflation; blowouts
question
Deflation leads to the formation of desert pavement by __________.
answer
carrying fine sediments away and leaving a layer of larger particles at the surface
question
In the first model, what happens as the layer of coarse material develops at the surface?
answer
It blocks the fine-grained sediment below from the wind, which prevents the possibility of further deflation.
question
In the second model, wind energy diminishes between large grains of the surficial layer, leading to what?
answer
deposition of fine-grained sediments between large grains
question
What is the primary difference between the two desert pavement hypotheses?
answer
Model 1 is based on a sediment volume decrease through time (erosion), while Model 2 is based on an increase in sediment volume through time (deposition).
