What is the main environmental concern associated with sulfur dioxide emissions?

  1. Depletion of the ozone layer
  2. Formation of acid rain ✓
  3. Global warming potential
  4. Depletion of the stratospheric ozone

Explanation

Sulfur dioxide forms acid rain. It reacts with water in clouds to make sulfuric acid. This acid damages plants, buildings, and water life.

CFCs deplete ozone, not SO₂. Carbon dioxide causes global warming. Sulfur dioxide’s main problem is acid rain.

Remember: Burning coal releases SO₂. Factories and power plants are major sources.
