Acid rain/deposition

Acid rain/deposition

• A. Produced by nitrogen oxides and sulfur oxides from man-made and natural resources
• B. Produced by chlorofluorocarbons
• C. Created by water vapor alone
• D. Does not occur naturally

Answer: (A)

Acid rain forms when sulfur dioxide and nitrogen oxides are released into the atmosphere and react with water to form sulfuric and nitric acids. These gases come from natural sources like volcanic eruptions and wildfires, as well as human activities such as burning fossil fuels and operating engines and factories. The acids then mix with precipitation, causing rain, snow, or fog to have a lower pH and affect soils, lakes, and plant life. The other ideas don’t fit because chlorofluorocarbons cause ozone depletion rather than acid deposition; water vapor alone does not create acid rain since it’s the reaction with these gases that produces the acids; and acid rain can and does occur from natural sources, though it is intensified by human emissions.
