Changes in the earth's crust: caused oxygen to fill the atmosphere.Scientists have wondered how the Earth's atmosphere was filled with oxygen. The oxygenation was waiting to happen. All he could have needed was for continents to ripen. The earth's atmosphere and early oceans were devoid of free oxygen, although tiny cyanobacteria produced gas as a by-product of photosynthesis. Free oxygen is oxygen that is not combined with other elements such as carbon or nitrogen, and aerobic organisms need it to live. A change occurred about three billion years ago, when small regions containing free oxygen began to appear in the oceans. Then, about 2.4 billion years ago, oxygen in the atmosphere suddenly increased by about 10,000 times in only 200 million years. This period, known as the Great Oxidation Event, completely changed the chemical reactions on the surface of the Earth.Before oxygenation, the continents were composed of rocks rich in magnesium and low in silica similar to what can be found today in places like Iceland and the Faeroe Islands. More importantly, these rocks contained a mineral called olivine. When olivine comes in contact with water, it initiates chemical reactions that consume oxygen and block it. That's probably what happened to the oxygen produced by cyanobacteria early in Earth's history. #ymasciencia
