Step 1
Which gas causes acid rain?
Answer
The gas that causes acid rain is sulfur dioxide (SO₂). When fossil fuels such as coal, oil, and natural gas are burned, sulfur dioxide is released into the atmosphere. Once in the atmosphere, sulfur dioxide can react with water to form sulfuric acid, which is a component of acid rain. Thus, the correct answer is D: Sulfur dioxide.
