If you ’re presently living on our sick blue dot , you should thank it for becoming inhabitable for us human folk . Specifically , you should face down and thank its mantle because scientists are saying that Earth ’s cooler mantle allowed it to acquire oxygen . You jazz , that matter we breathe to subsist .
research worker from Princeton University published a report in Nature that claims that our major planet ’s mantle was perfect for Earth ’s Great Oxygenation Event which occurred over 2.5 billion years ago and live around 900 million years . This was the period where “ O grade in the atmosphere exploded and finally give rise to our present atmosphere . ”
That all sound very important ! But why was the Earth ’s mantle so crucial to the GOE ? Because 2.5 billion year ago was when there was a acuate drib in mantelpiece thawing , the mantlepiece ( the layer between the Crust and the Core ) stopped set out as hot which break room for changes to occur . C. Brenhin Keller , lead author , and Blair Schoene , supporter prof at Princeton , wrote in the report that because of the declination in mantlepiece thawing , it also , fall the melting of the Earth ’s crust andaccording to Futurity.org , “ in bend reduced the yield of reactive , branding iron oxide - based volcanic gases into the atmosphere . A blue concentration of these gases — which respond with and remove oxygen from the atmospher — admit spare oxygen particle to proliferate . ”
That ’s why we have oxygen to take a breather . That ’s how the Earth became habitable . Thanks for continue it nerveless . study more about the report atFuturity . [ Futurity , Image CreditSergej Khakimullin / Shutterstock ]
