Acid rain, which is a form of’ air pollution, currently becomes a subject of great debate because of widespread environmental damage for which it has been blamed. It forms when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids, which may then be carried long distances from their source before they drop in the form of rain. The pollution may also take the form of snow or fog or fall down in dry forms. In fact, although the term "acid rain" has been in use .for more than a century--it is derived from atmospheric studies that were made in the region of Manchester, England--the more accurate scientific term would be’ acid deposition.’The dry form of such deposition is just as damaging to the environment as the liquid form.
