Question

Consider the following:
1. Oxides of Hydrogen
2. Oxides of Nitrogen
3. Oxides of Sulphur
Which of the above is/are causes/causes of acid rain?

• A. 1 and 2
• B. Only 3
• C. 2 and 3
• D. 1, 2, and 3

Hint:

To solve questions on environmental science, focus on understanding the role of chemical compounds in processes like acid rain formation.

Answer 1

The Correct Option is C

Acid rain is primarily caused by the presence of oxides of nitrogen (NOx) and oxides of sulfur (SOx) in the atmosphere. When these gases combine with water vapor, they form acidic compounds that lead to acid rain. Oxides of hydrogen are not a cause of acid rain. Therefore, the correct answer is 2 and 3.
