Carbon dioxide and methane as greenhouse gases
Question
- A. They decrease the amount of energy retained in the atmosphere
- B. They have no effect on temperature
- C. They increase the amount of energy retained in the atmosphere
- D. They only affect temperature during the day
Answer
The correct option is They increase the amount of energy retained in the atmosphere. This answer is correct because it matches the approved learning objective to distinguish the natural greenhouse effect from enhanced global warming caused by increased greenhouse gases in the subtopic Greenhouse gases.
Explanation
The correct option is They increase the amount of energy retained in the atmosphere. They increase the amount of energy retained in the atmosphere is correct because it directly supports the approved learning objective to distinguish the natural greenhouse effect from enhanced global warming caused by increased greenhouse gases. This belongs to the subtopic Greenhouse gases 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 Greenhouse gases.
Common mistake
Confusing Natural and Enhanced Greenhouse Effect
Students often confuse the natural greenhouse effect with enhanced global warming, thinking they are the same phenomenon.
To fix this, students should focus on understanding that the natural greenhouse effect is essential for maintaining Earth's temperature, while enhanced global warming refers to the additional warming caused by increased greenhouse gas concentrations due to human activities.
