The sulfuric and nitric acids pollute the rain (which is slightly acidic) and make it more acidic. This rain, polluted with nitric and sulfuric acids, is called acid rain . Sulfuric and nitric acids also affect snow, fog, and any type of precipitation, but to make things easier they will be collectively referred to as acid rain. Acid rain kills trees and aquatic life. No fish life in this lake. What causes acid rain? Acid rain is formed when nitric and sulfuric acids combine with natural rain. These acids are formed when SO 2 and NO 2 react with moisture in the air, but where do they come from? These gases can enter the air via car exhaust but the industrial smog (given off when coal is burned) is where most sulfur dioxide and nitrogen oxides come from. This is the reason why acid rain is
