Part 2 Answers: Acid Rain

1. When fossil fuels such as coal, oil and natural gas are burned, carbon dioxide, nitrogen oxides and sulfur dioxide escape into the air. These molecules dissolve in the water in the clouds and make the rainwater more acidic than normal. When this happens. it is called acid rain
