Question
- A. By trapping heat in the atmosphere
- B. By increasing solar radiation
- C. By reducing atmospheric pressure
- D. By promoting cloud formation
Answer
The correct option is By trapping heat in the atmosphere. This answer is correct because it matches the approved learning objective to explain how greenhouse gases help maintain temperatures on Earth in the subtopic Greenhouse gases.
Explanation
The correct option is By trapping heat in the atmosphere. By trapping heat in the atmosphere is correct because it directly supports the approved learning objective to explain how greenhouse gases help maintain temperatures on Earth. 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
Misunderstanding the Role of Greenhouse Gases
Students often think that greenhouse gases only trap heat without understanding their role in maintaining Earth's temperature.
Emphasize that greenhouse gases absorb infrared radiation emitted from the Earth's surface, which helps to maintain a stable temperature necessary for life.
