Acid rain is a form of precipitation that is significantly more acidic than normal rainwater, due to the presence of raised levels of sulfuric and nitric acids. It forms when sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions, primarily from industrial processes and vehicle exhaust, react with water vapor, oxygen, and other chemicals in the atmosphere. This reaction produces acidic compounds, which then fall to the ground as acid rain.
