Carbon dioxide and methane as greenhouse gases
Question
- A. It involves short-wavelength radiation from the Earth.
- B. It involves long-wavelength radiation from the Sun.
- C. It involves short-wavelength radiation from the Sun and infrared radiation emitted by the Earth.
- D. It involves the absorption of all types of radiation.
Answer
The correct option is It involves short-wavelength radiation from the Sun and infrared radiation emitted by the Earth.. This answer is correct because it matches the approved learning objective to recall that carbon dioxide, methane and water vapour are greenhouse gases in the subtopic Greenhouse gases.
Explanation
The correct option is It involves short-wavelength radiation from the Sun and infrared radiation emitted by the Earth.. It involves short-wavelength radiation from the Sun and infrared radiation emitted by the Earth. is correct because it directly supports the approved learning objective to recall that carbon dioxide, methane and water vapour are 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
