Sheet erosion, Pullman, Washington, 1946 Sheet erosion or sheet wash is the even erosion of substrate along a wide area. [1] It occurs in a wide range of settings such as coastal plains, hill slopes, floodplains, beaches, [2] savanna plains [3] and semi-arid plains. [4]
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
The complexities involved in studying sheet flows, including the need for advanced modeling techniques to accurately simulate flow dynamics and sediment transport mechanisms.
Colluvium (also colluvial material or colluvial soil) is a general name for loose, unconsolidated sediments that have been deposited at the base of hillslopes by either rainwash, sheetwash, slow continuous downslope creep, or a variable combination of these processes.

Charles Lyell, author of Principles of Geology, who established within the scientific community the concept of denudation and that idea that the surface of the Earth is shaped by gradual processes. The effects of denudation have been written about since antiquity, although the terms "denudation" and "erosion" have been used interchangeably ...
[3] However, for the rest of the century the more common term was "chemical geology", and there was little contact between geologists and chemists. [ 3 ] Geochemistry emerged as a separate discipline after major laboratories were established, starting with the United States Geological Survey (USGS) in 1884, which began systematic surveys of the ...
Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
