Acid rain is caused primarily by
- A
Particulate matter and soot (from diesel combustion) condensing with water in the lower atmosphere
- B
Carbon dioxide and methane (from fossil fuel combustion) dissolving into rainwater droplets
- Ccheck_circle
Sulfur and nitrogen oxides (from fossil fuel combustion) reacting with water in the atmosphere
- D
Ozone-depleting chlorofluorocarbons (from refrigerants) reacting with water in the stratosphere
Explanation
SO₂ → H₂SO₄, NO_x → HNO₃ in atmospheric water. Lowers pH of rainfall, harming forests and freshwater ecosystems.
