Deposition. Particles dropped from an erosional system due to a decrease in velocity of the agent  Dominant agent of erosion is running water  Most.

Deposition

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

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

Alluvial fan and Delta

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

Till and Moraines

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

Sand Dunes
