Acid Rain is a type of air pollution, which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids, which may then be carried long distances from a source before they are deposited by rain.

Acid rain is currently a subject of great controversy because of widespread environmental damage, for which …showed first 75 words of 417 total…
