摘      要：Key steps in atmospheric evolution occurred in the *** Hadean atmosphere was created by the inorganic processes of volatile accretion from space and degassing from the interior,and then modified by chemical and photochemical *** air was probably initially anoxic,though there may have been a supply of oxidation power as a consequence of hydrodynamic escape to space of hydrogen from *** subduction may have removed CO2 and the Hadean planet may have been *** the Archaean,as anoxygenic and then oxygenic photosynthesis evolved,biological activity remade the *** evidence implies there were liquid oceans despite the faint young *** oceans may have been sustained by the greenhouse warming effect of biologically-made *** in the late Archaean would have released free O2 into the *** would have created oxic surface waters,challenging the methane *** the Great Oxidation Event around 2.3 to 2.4 billion years ago,the atmosphere itself became oxic,perhaps triggering a glacial crisis by cutting methane-caused greenhouse *** the early Proterozoic,all the key biochemical processes that maintain the modern atmosphere were probably present in the microbial community.
