Deposition occurs when compounds of various types of air pollution are deposited on the Earth’s surface through rain, clouds, snow, fog, or particulates. The amount of deposition is affected by the concentration of pollutants in the atmosphere and how the pollutants are deposited. General factors, such as meteorology and topography, influence how much pollution…
