Acid rain is caused by the pollution of the environment by:

A) Carbon Dioxide and Nitrogen
B) Carbon Dioxide and Carbon Monoxide
C) Ozone and Carbon Dioxide
D) Nitrous Oxide and Sulphur Dioxide

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.
