1. WIND EROSION

2. Where is wind erosion most common?
Deserts
Beaches
Plowed Fields

3. 2 WAYS WIND ERODES

4. Deflation
Erosion caused by wind as it wears away sediments such as clay, silt, and sand
Wind will pick up small sediments and move them

5. ABRASION
A type of erosion caused when windblown or waterborne sand grains strike other sand grains and rocks, breaking off small sediments.
Similar to sandblasting
Sand grains and the rocks they strike become pitted and polished when small fragments are broken off.

7. DEPOSITION BY WIND

8. LOESS A thick deposit of very fine, wind eroded sediments
One of the larges deposits is near Mississippi River.
Fine as talcum powder
Fertile soil can evolve from loess deposits
Found in China, where sand and silt are blown from the deserts.

10. DUNES
Build up of sediments due to the sediments settle behind obstacles.
Most common wind deposits.
Form in deserts and beaches where sand is abundant.
