Acid raiñ"can belcaused by the combustion of fossil tuels, erupting volcanges, or rotting vegetation that releases sulfur dioxide and nitrogen oxide into the atmosphere. When fossil fuels such as coal, gasoline, and fuel oils are burned, they emit oxides of sulfur, carbon, and nitrogen into the air. These oxides combine with moisture in the air to form sulfuric acid, carbonic acid, and nitric acid. The term "acid rain" is also applied to other forms of precipitation-snow, hail, sleet, and fog-that are similarly acidic. During the 20th century, acid rain was recognized as a leading threat to the Earth's environment. Most acid rain comes from fossil fuel emissions produced in the industrialized northern hemisphere--the United States, Canada, Asia, and most of Europe. Acid rain is devastating to all forms of life, but its effects are especially severe in freshwater habitats such as lakes, rivers, and…arrow_forward
