Acid deposition/acid rain
A complex chemical and atmospheric phenomenon that occurs when emissions of sulfur (e.g. sulphuric oxide) and nitrogen compounds and other substances are transformed by chemical processes in the atmosphere, often far from the original sources and then deposited on earth in either a wet or dry form. The wet forms popularly called ?acid rain? and have a low pH. This can fall as rain, snow, or fog. The dry forms are acidic gases or particulates.
