Answer the following questions by selecting the correct/most appropriate options.


Which of the following gases are responsible for acid rain?
A. Nitrogen
B. Oxygen
C. Ozone
D. Sulphur dioxide
E. Nitric oxide

Correct option is C

The correct answer is: (c) D and E
Acid Rain: Acid rain is caused by the chemical reaction of certain gases in the atmosphere with water vapor. These gases are:
Sulfur dioxide (SO2): Primarily emitted from burning fossil fuels like coal and oil.
Nitrogen oxides (NOx): Including nitric oxide (NO) and nitrogen dioxide (NO2), these gases come from vehicle exhaust and industrial processes.
When these gases react with water vapor, oxygen, and other chemicals in the atmosphere, they form sulfuric and nitric acids. These acids then mix with rain, snow, or fog, making them acidic and causing the phenomenon known as acid rain.
