Presentation Transcript

  1. Erosion and Depostion By Emily Kaehn

  2. Erosion: The breaking down of rock and other material. The process by which sediments are laid down in a new location. Deposition

  3. Gravity Mass Wasting

  4. Mass Wasting: Downhill movement due to gravity.

  5. Wind Sand Dune Loess

  6. Loess Deposited by wind accumulation of fine particles. Sand Dune: A mound of sand deposed by the wind.

  7. Load Amount of sediment carried by a stream. Drainage System Streams and other running water flowing into a main river.

  8. Mature River A river that has been developing for thousands of years. Meander A loop in a river.

  9. Fan shaped deposit of sediments formed at the point where a river leaves the mountain and runs out onto the plain. Alluvial Fan Oxbow Lake A U-shaped lake caused when deposition and erosion cuts off meander in a river.

  10. Flood Plain Area on both sides of a river which is formed by sediments deposited during floods. Delta The mouth of a large river.

  11. Levee In nature a ridge like deposit along the sides of a river.

  12. Glacier Glacier Till Moraine Drumlin Meltwater Outwash Plain Ice Berg Kettle Lake

  13. Glacier Till The rocks and debris deposited directly by a glacier. A large mass of moving ice and snow.

  14. Drumlin An oval shaped mound of till Moraine A ridge of till left behind by a retreating glacier.

  15. Meltwater Outwash plain Fan shaped areas in front of terminal moraines formed by sediments deposited by rivers or glacial meltwater. Formed from the water of melting ice or snow.

  16. Iceberg A part of a glacier that has broken off and drifted into the sea. Kettle Lake A round deep lake formed a huge block of ice left behind by a glacier.
