... Using the 5.49 × 10 moles of SO2 estimated to have been released by the Matachewan LIP, we can calculate that the number of moles of O2 produced by these reactions would have 7.72 × 1016. This equates to a mass of O2 of 2.47 × 1015 kg. The mass of the modern atmosphere is approximately 5.15 × 1018 k ...

History of geology
The history of geology is concerned with the development of the natural science of geology. Geology is the scientific study of the origin, history, and structure of the Earth. Throughout the ages geology provides essential theories and data that shape how society conceptualizes the Earth.
