Wind and Gravity Erosion

The process by which the products of weathering are transported.

• Weathering
• Erosion

Where does wind erosion occur?

• Places where there is a lot of vegetation (plants, trees, grass)
• Places where there is little vegetation (plants, trees, grass)

Where does wind erosion occur?

• Places where there is little water in the soil
• Places where there is a lot of water in the soil

Wind removes topsoil, lowers the land and leaves rock fragments that are too large to be lifted.  Common in deserts.

• Deflation
• Abrasion
• Saltation
• Remediation

Rocks get worn down and smoothed mostly by blowing sand. This is called __________.

• Deflation
• Abrasion
• Saltation
• Remediation

Sand gets deposited by the wind and causes __________to form.

• Deflation
• Abrasion
• Mounds
• Dunes

Wind erosion generally occurs where there is a lot of vegetation and a lot of water.

• True
• False

Dunes are mounds of sand blown by the wind. 

• True
• False

How does wind abrasion work?

• Sediment is blown off a surface from wind.
• Wind-blown sediment strikes a surface.
• Wind blows large chunks of rock off a surface.
• Sediment falls off of a surface on its own.

Which type of land suffers the least from wind erosion?

• desert
• forest
• beach
• plowed fields
