Alluvial Fan: Unconsolidated sedimentary deposit that accumulates at the mouth of a mountain.Deposits are usually fan-shaped in plan view.
Deposits are fan-shaped, Distributary pattern of channels.Course grained, most poorly sorted deposits. |

Fluvial Environment: Rivers and valleys that were strongly affected by the climate changes.
Deposits are sometimes very thick and cover vast areas. Sediments become finer and corse grains become more rounded away from their sources. |

Lacustrine Environments: Larger lakes, that move back and forth in response to the major climate cycles or opening and closing of outlets due to glaciation.
.Lacustrine sediments are thought to have been derived from a series of saline lakes. |

Deserts: One-third of the Earth's land surface is desert, arid land with very little rainfall.
Some sedimentary deposits are bare rock(hamada) or deflated stony plain (serirs or reg).Sediments are the shape of a cone. |

Swamps: Wetland dominated by woody plants.A lot off organic material.
Nutrient releases in swamps are one of the deposits.Nitrogen and phosphorus removal by cypress swamp sediments.

Deltas: A low triangular area of alluvial deposits where a river divied before entering a large body of water.
If one area gets higher sedimentation than an ancient area, you can develop a bar that has topography.

Beaches: An area of sand sloping down to the water of a sea or lake.
River Sediments are the sources of 80-90% of Beach sand. |

Lagoons: A lagoon is a body of water cut off from a laqrger body by a reef of sand or coral.Salt marshes are found in lagoons. That is where muddy sediments,rich in organix material collects.

Continental Shelf:
A shallow seabed surrounding a continent.Shelf sediments decrease in grain size with increasing distance from the shore.Icebergs transport large sediment loads of various sizes onto the shelf. |

Tidal Flats: Mudflats are coastal wetlands that form when mud is depositied by tides or rivers.
Sediments found in Tidal Flats are sand,mud and marine shell gravel.
