Common atmospheric pollutants and their sources
Question
- A. They cause global warming.
- B. They contribute to acid rain.
- C. They produce carbon monoxide.
- D. They create soot particles.
Answer
The correct option is They contribute to acid rain.. This answer is correct because it matches the approved learning objective to explain that oxides of nitrogen form when nitrogen and oxygen react at high temperatures in engines in the subtopic Atmospheric pollutants from fuels.
Explanation
The correct option is They contribute to acid rain.. They contribute to acid rain. is correct because it directly supports the approved learning objective to explain that oxides of nitrogen form when nitrogen and oxygen react at high temperatures in engines. This belongs to the subtopic Atmospheric pollutants from fuels 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 Atmospheric pollutants from fuels.
Common mistake
Misunderstanding Nitrogen Oxides Formation
Students often confuse the formation of oxides of nitrogen with other pollutants, thinking they are produced from fuel impurities rather than from the reaction of nitrogen and oxygen at high temperatures.
Remember that oxides of nitrogen specifically form when nitrogen and oxygen react at high temperatures, such as in engine combustion, and are distinct from pollutants formed from fuel impurities.
