Q. By the emission of _ acid rain is caused.
Solution:
The correct answer is: Sulphur and Nitrogen
Acid rain is caused by the emission of pollutants, primarily:
- Sulfur dioxide (SO2)
- Nitrogen oxides (NOx)
These pollutants react with water, oxygen, and other chemicals in the atmosphere to form sulfuric acid and nitric acid, leading to acid rain.
Sulfur dioxide comes from:
- Burning fossil fuels (coal, oil, and gas)
- Industrial processes (smelting, refining)
Nitrogen oxides come from:
- Burning fossil fuels (especially vehicles)
- Industrial processes
- Agricultural activities
Acid rain can harm the environment, infrastructure, and human health.
The other options are not the primary causes of acid rain:
- Carbon is a component of many pollutants, but it’s not directly responsible for acid rain.
- Phosphorus is not typically associated with acid rain formation.
