Question
Acid rain happens because
- Sun leads to heating of the upper layer of the atmosphere.
- The burning of fossil fuels releases oxides of carbon, nitrogen, and sulfur in the atmosphere.
- Electrical charges are produced due to the friction amongst clouds.
- Earth's atmosphere contains acids.
Hint:
Acid rain is caused by emissions of acidic gases like Sulphur dioxide, nitrogen and carbon oxides, which react with the water molecules in the atmosphere to produce acids.
The correct answer is: Electrical charges are produced due to the friction amongst clouds.
Correct option is B)
