Describe acid deposition.

• Acid rain and deposition is due to nitrogen oxides and sulfur oxides from anthropogenic and natural sources in the atmosphere.
• Nitric oxides that cause acid deposition come from motor vehicles and coal-burning power plants. Sulfur dioxides that cause acid deposition come from coal-burning power plants.
• Enduring understanding STB-2: Human activities have physical, chemical, and biological consequences for the atmosphere.
