Answer:
Sulphur dioxide and nitrogen dioxide are the type of pollutants, which are released into the atmosphere by the burning of fossil fuels like diesel and coal. These pollutants react with the water vapours present in the atmosphere to form nitric acid and sulphuric acid respectively. By precipitation, these acids come down and form the acid rain.
Effects caused by the acid rain:
a) It destroys the crops.
b) Harmful for the building especially to those made of white marble like the Taj Mahal.
