  1. Aim: How can wind play a role in erosion and deposition? Do Now: Dunes can be found in most climates. Identify two environments where dunes can be located.

  2. Wind: Erosion and Deposition Depends on the following: • The of the sediment being carried. SIZE • The at which the wind is blowing. SPEED • The that the wind continues to blow. TIME

  3. Features Produced by Wind Deflation: wind picks up and carries away loose sediments.

  4. Dune Migration:is caused when prevailing winds continue to move sand from the windward side of a dune to its leeward side.

  5. Anatomy of a Dune

  6. Windward Side: gentle gradient and longer than leeward side. Leeward (Slipface) Side: Steep gradient and shorter than windward side.

  7. Mushroom-Shaped Rock: Only lower portions of exposed rock become eroded since sand, silt, and clay fragments are only lifted 1m into the air.

  8. Ventifacts: wind blown sand may sculpture pebbles, cobbles, or boulders.

  9. Rocks will have a frosted, pitted, and rounded appearance:

  10. Loess: Wind deposited silt composed of quartz, mica, and feldspar minerals. High agricultural potential.

  11. Summary: Winds transport sand and other materials by (1) water and rolling (2) suspension and bouncing (3) ice and snow (4) ocean currents and waves

  12. Of the material listed below, which is the most abrasive when blown across the ground surface? (1) quartz (2) gypsum (3) limestone (4) shale Which particle size is least likely to be found in a deposit of loess? (1) pebbles (2) sand (3) silt (4) clay
