Acid Rain in Pennsylvania Questions

1. Sulfur dioxide and nitrogen oxide are the gases that cause acid rain.
2. In Pennsylvania, most of the sulfur dioxide comes from power plants that burn coal (the coal has a lot of sulfur in it). Nitrogen oxide comes from power plants too, but it mostly comes from other sources: cars, fertilizers used in farming, lightning, etc.
3. Sulfur dioxide and nitrogen oxide in the atmosphere mix with water to form different acids. The acids then mix in with rain, making acid rain.
