Presentation Transcript

  1. Deposition

  2. Definition • Deposition- the process in which sediment is laid down in new locations • The end result of erosion

  3. Water Deposition • Alluvial fan- fan shaped deposit of sediment on land • Usually form when a stream slows down and enters a flat plain • Delta- sediment from a stream deposited where a river enters a large body of water • Triangular shape

  4. Alluvial fan and Delta

  5. Glacial Deposition • As a glacier melts, it creates landforms by depositing its sediment load • Till-unsorted mixture of sediment containing fragments of various sizes • Moraine-mounds of sediment at the downhill end of the glacier and along its side • Long Island is a glacial moraine

  6. Till and Moraines

  7. Wind Deposition • Sand dunes- large deposits of sand dropped from wind • Sand dunes can move as the wind picks up sand from the back of the dune and blows it to the front
