Detailed explanation-1: -Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.
Detailed explanation-2: -Acid rain is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, where they react with water, oxygen, and other chemicals to become sulfuric and nitric acid respectively.
Detailed explanation-3: -Acid rain is caused by emissions of acidic gases like sulphur dioxide, nitrogen and carbon oxides, which react with the water molecules in the atmosphere to produce acids.
Detailed explanation-4: -Sulfur dioxide and nitrogen oxides, the major sources of acid rain, can irritate or even damage our lungs.
