Weathering Environments Part 2: Aeolian Processes

The video tutorial covers aeolian weathering, focusing on the transportation, erosion, and deposition of sediments by wind. It explains how wind erosion occurs through abrasion and deflation, and describes the formation of various types of sand dunes based on wind direction. The tutorial also explores the presence of dunes on Mars and Titan, highlighting their unique characteristics. The session concludes with a transition to discussing glacial processes.

What is the primary factor that limits the size of sediment that wind can transport on Earth?

• The temperature of the environment

• The humidity levels

• The presence of vegetation

• The density of air

• Deflation

• Abrasion

• Traction

• Saltation

What type of sand dune forms perpendicular to the prevailing wind direction and has straight crests?

• Star dunes
