Every deck we have for Chemistry of the Atmosphere, part of AQA GCSE Chemistry. 72 questions written against the published specification, free to study with no account. Each deck schedules its own reviews, so cards you find hard come back sooner than ones you have already got right.
What the early atmosphere was made of, how the oceans formed, how oxygen appeared and carbon dioxide fell, and why the evidence is uncertain.
How the greenhouse effect actually works, the human activities driving it, the predicted consequences, and what a carbon footprint is and how to reduce it.
Carbon monoxide, soot, sulfur dioxide and oxides of nitrogen: where each comes from and the problems each one causes.
Chemistry of the Atmosphere is one topic of AQA GCSE Chemistry. The other topics are all covered too, in the same format.
