Acid deposition, commonly known as acid rain, is primarily caused by the emission of which two major classes of gaseous pollutants into the atmosphere?

💡 Explanation:

Acid rain results when sulfur dioxide (SO₂), largely from coal burning power plants, and nitrogen oxides (NOₓ), often from vehicle emissions, are released into the atmosphere, where they react with water, oxygen, and other substances to form acidic compounds like sulfuric and nitric acid.
