KnowraOxygenation of Earth's atmosphereLinked fromLinked fromThe 9 pages that link to Oxygenation of Earth's atmosphere, each with the reason it gives.All 9Related 9Banded iron formationRelated: Oxygen produced by early life helped convert dissolved iron into iron oxides that settled on the seafloor.CambrianRelated: Changing oxygen availability is one proposed environmental influence on animal diversification.MicroorganismRelated: Ancient microorganisms helped transform the planet's atmosphere.Iron(III) oxideRelated: Early oxygen reacted with dissolved iron, helping precipitate iron oxides in ancient oceans.Kaapvaal CratonRelated: Craton sediments help trace how environmental change unfolded before and during oxygenation.ProterozoicRelated: Researchers continue to debate the timing, pace, and causes of Proterozoic oxygen increases.Marinoan glaciationRelated: Researchers investigate whether postglacial environmental changes affected oxygen levels and early ecosystems.Biological carbon fixationRelated: Photosynthetic carbon fixation helped release oxygen while organic carbon accumulated.Microbiological phenomenaRelated: Microbial photosynthesis transformed Earth's atmosphere and enabled oxygen-dependent life.
