Explain how the removal of carbon dioxide from the atmosphere is linked to changes in the carbon cycle.

The removal of carbon dioxide from the atmosphere is linked to the carbon cycle through processes such as photosynthesis, where plants absorb carbon dioxide to produce oxygen and organic matter. Additionally, carbon dioxide dissolves in oceans and forms carbonate minerals, which further reduces atmospheric levels and contributes to sediment formation.

A strong answer should directly address the approved learning objective to link carbon dioxide removal to changes in the carbon cycle. This question belongs to How carbon dioxide decreased 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 cycle, and keeps the wording specific to AQA GCSE revision.
