1. 7.3 Landscapes Shaped by Wind

2. Wind Erosion
Strong desert winds pick up, transport, & deposit large amounts of fine sediment
Wind erodes in the desert in 2 ways: deflation & abrasion
Deflation is the lifting & removal of loose particles such as clay & silt

3. Wind Deposits Loess is windblown silt that covers the land
The wind can create landforms when it deposits its sediment
Loess & sand dunes are both landscape features made by wind
Sand dunes are not as wide spread (do not cover as much land) as loess

4. Types of Sand Dunes
What form sand dunes take on depends on wind direction & speed, how much sand is available, & the amount of vegitation
6 Types of sand dunes
Barchan Dunes
Transverse Dunes
Barchanoid Dunes
Longitudinal Dunes
Parabolic Dunes
Star Dunes
