The Great Oxygenation Event (GOE), also called the Oxygen Catastrophe, Oxygen Crisis, Oxygen Holocaust, Oxygen Revolution, or Great Oxidation, was the biologically induced appearance of dioxygen (O 2) in Earth's atmosphere.he gap between the start of oxygen production from photosynthetic organisms and the geologically rapid increase in atmospheric oxygen (about 2.5â2.4 billion years ago) may have been as long as 900 million years.
The structure shown above is oxygen's cubic crystal element structure. Oxygen exists in all three forms-liquid, solid, and gas. The liquid and solid forms are a pale blue colour. However, oxygen gas is colourless, odourless, and tasteless.The elemental structure is a cubic crystal shape. Oxygen changes from a gas to a liquid at a temperature of 182.96Â°C, and then can be solidified or frozen at a temperature of -218.4Â°C. Oxygen exists in all three allotropic forms.owever, oxygen gas is colourless, odourless, and tasteless. The elemental structure is a cubic crystal shape.
