Answer: Acid rain contains sulphuric acid, nitric acid (and carbonic acid), formed when sulphur dioxide, nitrogen oxides and CO2 dissolve in rain water.
Effects:
- It makes soil and water bodies acidic, which lowers soil fertility and harms crops, forests and aquatic animals.
- It corrodes buildings, monuments (especially marble, e.g. the Taj Mahal), bridges and metal structures.
