Carbon dioxide and methane as greenhouse gases
Question
- A. They decrease global temperatures.
- B. They are linked to global climate change.
- C. They have no impact on the climate.
- D. They only affect air quality.
Answer
The correct option is They are linked to global climate change.. This answer is correct because it matches the approved learning objective to explain that increased greenhouse gas concentrations are linked to global climate change in the subtopic Global climate change.
Explanation
The correct option is They are linked to global climate change.. They are linked to global climate change. is correct because it directly supports the approved learning objective to explain that increased greenhouse gas concentrations are linked to global climate change. This belongs to the subtopic Global climate change within Carbon dioxide and methane as greenhouse gases, 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 Global climate change.
Common mistake
Linking Greenhouse Gases to Climate Change
Students often confuse the correlation between increased greenhouse gas concentrations and global climate change with causation, believing that one directly proves the other.
Emphasize that correlation does not imply causation and that while increased greenhouse gases are linked to climate change, other factors may also contribute to climate variations.
