Recall that the Earth's atmosphere contains small proportions of other gases including carbon dioxide, water vapour and noble gases.

Recall that the Earth's atmosphere contains small proportions of other gases including carbon dioxide, water vapour and noble gases. This objective belongs to The proportions of different gases in the atmosphere within The composition and evolution of the Earth's atmosphere for AQA GCSE Chemistry 8462. A strong answer should use atmosphere accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
