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: -Burning coal puts different gases into the air. Some of these gases are called sulfur dioxide and nitrogen oxides. These gases mix with water droplets and oxygen (another gas) to make chemicals called sulfuric acid and nitric acid.

Detailed explanation-3: -Acid rain can be formed by natural causes, such as volcanic eruptions. More commonly, however, acid rain is due to human activities. Burning fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles all release sulfur and nitrogen oxides into the atmosphere.

Detailed explanation-4: -What are its harmful effects? It has been shown that acid rain has detrimental effects on trees, freshwaters and soils, destroys insects and aquatic life-forms, causes paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and sculptures, as well as impacts on human health.
