acid rain
Rain, snow, or other precipitation containing a high amount of acidity.
Did You Know? We normally think of rain as something pure and natural, but in many parts of the world it is polluted with harmful acids from the moment it forms in the sky. How does this happen? When coal, gasoline, and oil are burned as fuels, they give off the gases sulfur dioxide and nitrogen oxide. In the atmosphere, these compounds combine with water vapor to form highly corrosive sulfuric and nitric acids. Prevailing winds carry these acids away from the industrial areas where they originate, and they fall to earth as acid rain. Acid rain is a serious environmental problem in parts of the world where there are many factories, power plants, and automobiles close together, as in parts of the United States, Canada, Europe, and Asia. It harms forests and soils and pollutes lakes and rivers, killing fish and other aquatic life. It can also damage buildings and monuments by eating away the stone and metal that they are made of.

acid rain
Rain acidified by sulfuric, nitric, and other acids that form when water and sunlight react with sulfur dioxide, nitrogen oxides and other pollutants released by burning fossil fuels. Acid rain can poison lakes, kill forests, and corrode buildings.
