In chemistry, deposition is the settling of particles (atoms or molecules) or sediment from a solution or suspension mixture, or the production of a solid on a pre-existing surface. Image File history File links Please see the file description page for further information. ... Deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid. ... Chemistry (from the Greek word χημεία (chemeia) meaning cast together or pour together) is the science of matter at the atomic to molecular scale, dealing primarily with collections of atoms (such as molecules, crystals, and metals). ... Properties For other uses, see Atom (disambiguation). ... In chemistry, a molecule is an aggregate of at least two atoms in a definite arrangement held together by special forces. ... Sediment is any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water or other liquid. ... Dissolving table salt in water In chemistry, a solution is a homogeneous mixture composed of one or more substances, known as solutes, dissolved in another substance, known as a solvent. ... Flour suspended in water In chemistry, a suspension is a colloidal dispersion (mixture) in which a finely-divided species is combined with another species, with the former being so finely divided and mixed that it doesnt rapidly settle out. ... An open surface with X-, Y-, and Z-contours shown. ...

The term is also widely used in earth science to describe the same process in a geological sense. Deposition of particles is an aggradational process — one that builds a landform — as opposed to a degradational process that erodes or reduces the size of a landform. For example, a river mouth delta is formed by deposition of sediment carried by the stream as the river current diminishes upon encountering the sea. Earth science (also known as geoscience, the geosciences or the Earth Sciences), is an all-embracing term for the sciences related to the planet Earth. ... Deposition, also known as sedimentation, is the geological process whereby material is added to a landform. ... A landform comprises a geomorphological unit. ...
