Question

which environmental issue is exacerbated when sulfur dioxide erupts from volcanoes?
global warming
water pollution
deforestation
acid rain

Explanation:

Sulfur dioxide (SO₂) released from volcanoes reacts with water vapor, oxygen, and other chemicals in the atmosphere to form sulfuric acid. This acid dissolves in water droplets and falls to the ground as acid rain, worsening this environmental issue. Global warming is driven more by greenhouse gases like CO₂, water pollution is not the primary direct effect of volcanic SO₂, and deforestation is unrelated to volcanic sulfur dioxide emissions.

Answer:

acid rain
