Question
- A. By increasing the amount of carbon in the atmosphere
- B. By forming fossil fuels from marine organisms
- C. By creating sedimentary rocks from carbonate precipitates
- D. By releasing oxygen into the atmosphere
Answer
The correct option is By creating sedimentary rocks from carbonate precipitates. This answer is correct because it matches the approved learning objective to explain that carbon dioxide dissolved in the oceans as the atmosphere changed in the subtopic How carbon dioxide decreased.
Explanation
The correct option is By creating sedimentary rocks from carbonate precipitates. By creating sedimentary rocks from carbonate precipitates is correct because it directly supports the approved learning objective to explain that carbon dioxide dissolved in the oceans as the atmosphere changed. This belongs to the subtopic How carbon dioxide decreased 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 How carbon dioxide decreased.
Common mistake
Misunderstanding Carbon Dioxide Dissolution
Students often think that carbon dioxide simply disappears from the atmosphere without any process involved.
Emphasize that carbon dioxide dissolves in the oceans, which is a key process in the changing composition of the atmosphere.
