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 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-3: -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-4: -Effects of Acid Rain on Plants and Trees Dead or dying trees are a common sight in areas effected by acid rain. Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.

Detailed explanation-5: -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.
