Carbon dioxide and methane as greenhouse gases
Question
- A. Oxygen
- B. A related atmosphere statement, but it misses the evidence angle required here.
- C. A misconception that belongs to a neighbouring Chemistry of the atmosphere objective.
- D. A vague claim that does not connect Greenhouse gases to the specification point.
Answer
The correct option is Oxygen. For this evidence question, that option is correct because it matches Define greenhouse gases as gases that absorb infrared radiation emitted from the Earth's surface in Greenhouse gases.
Explanation
Oxygen is the correct answer for this AQA GCSE Chemistry atmosphere question. Separate a supported conclusion from a claim that goes beyond the evidence. The learning objective is: Define greenhouse gases as gases that absorb infrared radiation emitted from the Earth's surface. In Carbon dioxide and methane as greenhouse gases, this means the explanation must use the subtopic Greenhouse gases and avoid drifting into a different gas, pollutant, climate, or early-atmosphere idea. Checkpoint 4: this page uses the evidence angle so students can practise one distinct reasoning route before moving to the next question.
Common mistake
Misunderstanding Greenhouse Gases
Students often confuse greenhouse gases with all gases in the atmosphere, thinking all gases absorb infrared radiation.
Remember that greenhouse gases specifically absorb infrared radiation emitted from the Earth's surface, not all gases.
