Question
- A. Carbon dioxide
- B. Carbon monoxide
- C. Sulfur dioxide
- D. Oxides of nitrogen
Answer
The correct option is Carbon monoxide. This answer is correct because it matches the approved learning objective to explain that oxides of nitrogen can cause acid rain in the subtopic Properties and effects of atmospheric pollutants.
Explanation
The correct option is Carbon monoxide. Carbon monoxide is correct because it directly supports the approved learning objective to explain that oxides of nitrogen can cause acid rain. This belongs to the subtopic Properties and effects of atmospheric pollutants within Common atmospheric pollutants and their sources, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Properties and effects of atmospheric pollutants.
Common mistake
Misunderstanding Nitrogen Oxides
Students often confuse oxides of nitrogen with sulfur dioxide when explaining their role in acid rain.
Clarify that oxides of nitrogen, formed from nitrogen and oxygen at high temperatures, specifically contribute to acid rain, while sulfur dioxide comes from burning sulfur impurities in fuels.
