Question
- A. Neon
- 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 The proportions of different gases in the atmosphere to the specification point.
Answer
The correct option is Neon. For this evidence question, that option is correct because it matches Recall that the Earth's atmosphere contains small proportions of other gases including carbon dioxide, water vapour and noble gases in The proportions of different gases in the atmosphere.
Explanation
Neon 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: Recall that the Earth's atmosphere contains small proportions of other gases including carbon dioxide, water vapour and noble gases. In The composition and evolution of the Earth's atmosphere, this means the explanation must use the subtopic The proportions of different gases in the atmosphere and avoid drifting into a different gas, pollutant, climate, or early-atmosphere idea. Checkpoint 20: this page uses the evidence angle so students can practise one distinct reasoning route before moving to the next question.
Common mistake
Common Mistake in Gas Proportions
Students often confuse the proportions of carbon dioxide and noble gases in the atmosphere, thinking noble gases are more abundant.
Remember that noble gases are present in very small amounts compared to carbon dioxide, which is also a minor component but more significant than noble gases.
