Formation of earth atmosphere

WebThe ocean and atmosphere would, therefore, have started to form even as the Earth formed. The new atmosphere probably contained water vapor , carbon dioxide, nitrogen, and smaller amounts of other gases. WebThese volatiles are thought to have formed the early atmosphere of Earth. At an initial crustal temperature of about 600 °C (about 1,100 °F), almost all of these compounds, including water (H 2 O), would have been in the atmosphere. The sequence of events that occurred as the crust cooled is difficult to reconstruct.
