Question
- A. Nitrogen
- B. Oxygen
- C. Carbon Dioxide
- D. Hydrogen
Answer
The correct option is Hydrogen. Hydrogen is correct because it matches the greenhouse-gas mechanism required for The proportions of different gases in the atmosphere.
Explanation
Hydrogen is the correct option. Focus on how the gas changes heat retention or climate, not the whole atmospheric timeline. This answer supports the approved objective: Distinguish the major gases in the present atmosphere from trace atmospheric gases. In The proportions of different gases in the atmosphere, a correct response must stay within The composition and evolution of the Earth's atmosphere and avoid borrowing wording from a neighbouring atmospheric chemistry objective.
Common mistake
Confusing Major and Trace Gases
Students often confuse major gases like nitrogen and oxygen with trace gases such as carbon dioxide and noble gases.
To fix this, students should memorize the major gases in the atmosphere and understand that trace gases are present in much smaller amounts.
