Briefly explain why sand is moved by wind before clay and silt during wind erosion. What will be an ideal response?
A very thin layer of motionless air lies next to the ground, so there is less wind there. Sand grains
protrude above the surface and are more easily caught by the wind, while clay and silt grains lie closer
to the surface and will not be picked up unless the stationary layer of air is disturbed.
