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.
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process . The reverse of deposition is sublimation and hence sometimes deposition is called desublimation .
In chemistry, deposition occurs when molecules settle out of a solution. Deposition can be defined as the process of direct transition of a substance from its gaseous form, on cooling, into a solid state without passing through the intermediate liquid state. [1] Deposition can be viewed as a reverse process to dissolution or particle re ...
Sedimentation is the deposition of sediments. [1] It takes place when particles in suspension settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or ...
The reverse process of sublimation is deposition (also called desublimation), in which a substance passes directly from a gas to a solid phase, without passing through the liquid state. [4] Technically, all solids may sublime, though most sublime at extremely low rates that are hardly detectable under usual conditions.
Electrohydrodynamic deposition (electrospray deposition) is a relatively new process of thin-film deposition. The liquid to be deposited, either in the form of nanoparticle solution or simply a solution, is fed to a small capillary nozzle (usually metallic) which is connected to a high voltage.
Deposition may refer to: Deposition (law) , taking testimony outside of court Deposition (politics) , the removal of a person of authority from political power
[5] [6] The transport of eroded materials from their original location is followed by deposition, which is arrival and emplacement of material at a new location. [1] While erosion is a natural process, human activities have increased by 10–40 times the rate at which soil erosion is occurring globally. [7]
