The natural process of atmospheric and environmental agents, such as wind, rain, and temperature changes, disintegrate, and decompose rocks.

The mechanical breakdown of rocks into smaller pieces that is caused by natural processes and that does not change the chemical composition of the rock material.

The process of when rock is reduced in sized by scraping of other rocks driven by water, wind, and gravity.

The chemical breakdown and decomposition of rocks by natural processes in the environment

A chemical reaction in which a material combines with oxygen to form new material; in geology, oxidation is a form of chemical weathering.

Precipitation, such as rain, sleet, or snow that contains a high concentration of acids, often because of the pollution of the atmosphere.

The process by which wind, water ice, or gravity transports soil and sediment from one location to another.

The process in which material is laid down

An area along the river that forms from sediments deposited when the river overflows its banks.

A mass of material deposited in a triangular or fan shape at the mouth of a river or stream.

A fan-shaped mass of rock material deposited by a stream when the slope of the land decreases sharply.

The water that is beneath Earth's surface.

The boundary between land and a body of water.

An area of the shoreline that is made of deposited sand.

A low ridge of sand deposited along a lake or sea.

A long ridge of sand or narrow that lies parallel to the shore.

A mount of wind deposited sand that moves as a result of the action of wind.

Fine-grained sediments of the Quartz, Feldspar, Hornblende, Mica, and clay deposited by the wind.

A large mass of ice that exists year-round, and moves over land.

The rock material carried and deposited by glaciers.

the slowed downhill movement of weathered rock material.

The rapid mass movement of rock down a steep slope or cliff.

The sudden movement of rock and soil down a slope.

The flow of a mass of mud or rock and soil mixed with a large amount of water.

An area of significantly increased elevation on Earth, usually rising to the summit.

A filled or partially filled basin of fresh water or salt water surrounded by land.

A large natural stream of water that flows across land surfaces within a channel.

A location where land and ocean surface meet.
