The process in which chemical reactions alter or destroy minerals when rock comes in contact with water solutions and/or air
Naturally formed cracks in rocks
The process in which intact rock breaks into smaller grains or chunks
An accumulation of loose mineral grains, such as boulders, pebbles, sand, silt, or mud, that are not cemented together
Sediment that has undergone changes at the surface of the Earth, including reaction with rainwater and the addition of organic material
The removal of soil by wind and runoff
Distinct zones within a soil, distinguished from each other by factors such as chemical composition and organic content
A vertical sequence of distinct zones of soil
The processes that break up and corrode solid rock, eventually transforming it into sediment
Zone of accumulation
The layer of regolith in which new minerals precipitate out of water passing through, thus leaving behind a load of fine clay
Zone of leaching
The layer of regolith in which water dissolves ions and picks up very fine clay; these materials are then carried downward by infiltrating water
