'''Deposition''' is a process in which [[gas]] transforms into [[solid]] without going through the [[liquid]] state. The reverse of deposition is [[sublimation]].
One example of deposition is the process by which, in sub-freezing air, [[water]] vapor changes directly to [[ice]] without first becoming a liquid. This is how [[snow]] forms in [[cloud]]s, as well as frost and hoar frost on the ground.
Another example of physical deposition is the artificial process of physical vapor deposition, used to deposit thin films of various materials onto various surfaces.
