Short explanation
Recall that volcanoes released carbon dioxide, water vapour and nitrogen. This objective belongs to The Earth's early atmosphere within The composition and evolution of the Earth's atmosphere for AQA GCSE Chemistry 8462. A strong answer should use carbon dioxide 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.
