the natural, in place breakdown of rocks, minerals, and soils on Earth’s surface caused by physical, chemical, and biological processes

the process of breaking down rocks, minerals, and soils into smaller pieces without changing their chemical composition

the mechanical process of wearing, grinding, or scraping away surfaces through friction and impact, caused by moving particles in wind, water, or ice

breaks down rocks by altering their molecular structure through chemical reactions

a type of chemical weathering where metallic minerals within rocks, especially iron, react with oxygen and water to form oxides

a form of accelerated chemical weathering where precipitation (rain, snow, fog) containing high levels of sulfuric and nitric acids

the geological process of wearing away and transporting soil, rock, and sediment from the Earth’s surface, primarily driven by water, wind, ice, and gravity

he geological settling of sediments

A floodplain is a generally flat or low-lying area of land adjacent to a river, stream, lake, or ocean

a landform created by deposited sediment at a river's mouth

alluvial fans form on land at mountain bases with coarser, angular sediment

water located beneath the Earth's surface

the line along which a large body of water meets the land.

a strip of land covered with sand

a long, narrow, offshore deposit of sand and sediment that runs parallel to the mainland coast

a mound or ridge of sand or other loose sediment formed by the wind

a fine-grained, porous, and yellowish-brown soil formed by the wind-blown accumulation of silt-sized sediment

a slowly moving mass or river of ice

a general geological term for all rock material ranging from boulders and gravel to sand and clay transported and deposited by glaciers or their meltwater

the slow, permanent deformation of solid materials under long-term, constant stress, often exacerbated by high temperatures

the sliding down of a mass of earth or rock from a mountain or cliff.

a fluid or hardened stream or avalanche of mud.

a large natural elevation of the earth's surface rising abruptly from the surrounding level; a large steep hill.

a large body of water surrounded by land.

a large natural stream of water flowing in a channel to the sea, a lake, or another such stream.

the outline of a coast, especially with regard to its shape and appearance.
