In the desert, a soil mixture of sand and small rocks is exposed to wind erosion.

How would the land surface change over time?

• wind would pick up sediment making it fall on top of each other creating sand dunes

• wind would pick up sediment making it fall on top of each other creating sand mountins

• wind would pick up sediment making it fall on top of each other creating lime stone

What are two kinds of wind erosion?
