Question

Write a short note on Acid Rain.

Answer 1

1. When pollutants combine with water vapor in the presence of sunlight and oxygen, they form dilute sulphuric and nitric acids in the atmosphere.
2. When this mixture precipitates from the atmosphere, it is called acid rain.
3. The gases that cause acid rain are sulfur dioxide, nitrogen oxides, carbon dioxide, and other minute bio-products caused by the burning of fossil fuels.
