Changes Minor clarification changes to original content New Key Idea 2 – “Fossils provide evidence of
increasing diversity of life through geological time”. Knowledge has been clarified to highlight stages in the development of life and mass extinctions.
e.g. Ediacaran fauna, Cambrian explosion, migration to life on land, causes of extinction events.

New Key Idea 3 “ A combination of global factors contributes to climate change through geological time.”
Continent and montain belt distribution Milankovitch cycles Greenhouse gas changes and natural processes Rates of past and present climate change.
Key Idea 3: A combination of global Key Idea 3: A combination of global factors contributes to climate change factors contributes to climate change
through geological timethrough geological time
(a) The distribution of continents and mountain belts controls oceanic and atmospheric circulation and influences global climate;
(b) Milankovitch cycles as a contributory cause of ice ages.
(c) Atmospheric composition: the concentration of CO2 and methane, and natural and man-made contributions ….;
(d) Rates of past and present changes.
