Eolian Processes
- Eolian transport mechanisms - suspension, saltation and creep
- Erosional features
- Desert Pavement - what it is and how it forms
- Yardangs and Ventifacts - what it is and how it forms
- Quiz 7: What is desert pavement, and how does it form? (A diagram might help)
- Depositional Features
- Sand dunes - description and definition of types of sand dunes (eg. stoss slope, slipface) (include diagram).
- Erg deserts - where can you find them and why are they where they are. (can you show them on a map?)
- Leoss - what is leoss and where can it be found (and why is it found there)
[edit]
Desert features
- Alluvial fans - what are they and how/why do they form
- Tallus slopes - what are they and how/why do they form
- Playas - what are they and how do they form (why are playas salty and other lakes not)
- Slot canyons - what are they and how/why do they form
- EC: How do alluvial fans form? Use the terms:
- Carrying capacity
- sediment load
- grain size
- desert varnish
- avulsion
- lobe
