Loess

3. Wind Erosion
deflation ~ this means to “blow away”

4. Wind Erosion
deflation
desert pavement~ this is what is left after the small stuff has blown away. This is
near Reno, Nevada.

5. Wind Erosion
deflation hollow~ the deflation has left a hole. In the Sandhills, we call this a
“blowout”

6. Wind Erosion
ventifacts~ rocks smoothed by wind erosion. This one is in Antarctica.

7. Wind Erosion
ventifacts~ rocks smoothed by wind erosion. This one is in not.

8. Dunes
barchan

9. The open face (slip face) faces away from the wind.

10. The open face (slip face) faces away from the wind.

12. parabolic
transverse
longitudinal

13. Loess

14. Wind moves sand by a process known as
Saltation c. Emergence
Abrasion d. Depression

15. The most common kind of wind erosion is
Migration c. Saltation
Abrasion d. Deflation

16. Sand dunes move primarily by
Abrasion c. Migration
Deflation d. Submergence
