WebTwo billion years ago, the Earth’s atmosphere consisted of water vapor, carbon dioxide, methane, and ammonium, with little or no free oxygen. Supposedly, the high content of greenhouse gases in the ancient Earth’s atmo sphere, primarily. carbon dioxide, methane, and water vapor, prevented heat radiation loss into space. WebEruptions put water vapor, carbon dioxide and other gases into the air that helped create Earth's early atmosphere. Slowly, two processes changed Earth's atmosphere to one that is more oxygen-rich—like the one we have today. First, radiation from the Sun caused water vapor molecules to split apart.
