great oxidation event









































the great oxidation event (goe), sometimes also called the great oxygenation event, oxygen catastrophe, oxygen crisis, oxygen holocaust, or oxygen revolution, was when earth's atmosphere and the shallow ocean experienced a rise in oxygen around 2.4 billion years ago (2.4 ga) to 2.1-2.0 ga during the paleoproterozoic era. geological, isotopic, and chemical evidence suggests that biologically induced molecular oxygen (dioxygen, o) started to accumulate in earth's atmosphere and changed earth's atmosphere from a weakly reducing atmosphere to an oxidizing atmosphere. the causes of the event remain unclear.
