Acid rain refers to precipitation in the form of rain, snow, sleet, or fog that contains unusually high amounts of acidic components, primarily sulfuric and nitric acids. It is caused by the release of sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) into the atmosphere, mainly from human activities such as burning fossil fuels in power plants, factories, and vehicles.
