Pollutants like sulphur dioxide and nitrogen dioxide react with the water vapour present in the atmosphere to form sulphuric acid and nitric acid respectively. The acids drop down with rain, making the rain acidic. This is called acid rain.

Acid rain affects us in many ways:

(i) Acid rain corrodes the marble of the monument.

(ii) Acidic rain when flows through the soil leach out the aluminum present and flows into the rivers. It is harmful to aquatic animals.

(iii) Acid rain also removes minerals and nutrients from the soil that trees need to grow.
