- Rain containing excess acid is called acid rain.
- The rain becomes acidic because of carbon dioxide, sulphur dioxide and nitrogen dioxide in the atmosphere (which are released into the air as pollutants).
- These pollutants dissolve in rain drops to form carbonic acid, sulphuric acid and nitric acid respectively.
- Acid rain can cause damage to buildings, historical monuments, plants, crops and animals.
