Question
What gases were released by volcanoes during the formation of the Earth's early atmosphere?
Answer
Volcanoes released carbon dioxide, water vapour, and nitrogen during the formation of the Earth's early atmosphere.
Explanation
A strong answer should directly address the approved learning objective to recall that volcanoes released carbon dioxide, water vapour and nitrogen. This question belongs to The Earth's early atmosphere within The composition and evolution of the Earth's atmosphere, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to carbon dioxide, and keeps the wording specific to AQA GCSE revision.
Common mistake
Misunderstanding Gas Release
Students often confuse the gases released by volcanoes, thinking they only released carbon dioxide and ignoring water vapour and nitrogen.
Remember that volcanoes released carbon dioxide, water vapour, and nitrogen. It's helpful to create a list of all gases released during volcanic activity.
