Question
- A. Oxygen, nitrogen, and methane
- B. Carbon dioxide, water vapour, and nitrogen
- C. Hydrogen, helium, and carbon monoxide
- D. Sulfur dioxide, ammonia, and argon
Answer
The correct option is Carbon dioxide, water vapour, and nitrogen. This answer is correct because it matches the approved learning objective to recall that volcanoes released carbon dioxide, water vapour and nitrogen in the subtopic The Earth's early atmosphere.
Explanation
The correct option is Carbon dioxide, water vapour, and nitrogen. Carbon dioxide, water vapour, and nitrogen is correct because it directly supports the approved learning objective to recall that volcanoes released carbon dioxide, water vapour and nitrogen. This belongs to the subtopic The Earth's early atmosphere within The composition and evolution of the Earth's atmosphere, 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 The Earth's early atmosphere.
Common mistake
Misunderstanding Gas Release
Students often confuse the gases released by volcanoes, thinking they only released carbon dioxide and ignoring water vapour and nitrogen.
Remember that volcanoes released carbon dioxide, water vapour, and nitrogen. It's helpful to create a list of all gases released during volcanic activity.
