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

Water DepositionWater 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

Glacial DepositionGlacial 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

Wind DepositionWind 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
