Chemistry of the Earth's Atmosphere for AQA GCSE Chemistry and Combined Science

This is a revision video aimed at students taking AQA GCSE Chemistry (i.e. the 8462 specification) or Combined Science (the 8464 specification). It covers the Earth's early atmosphere, changes to the modern atmosphere and how human activities have made a large impact in the last 200 years. There are some bits from my full Paper 2 video (   • Friday 12th June 2026 - AQA GCSE Chemistry...  ) but also some further detail that isn't in the crammer video.
