Sentences with phrase «oxygen rich atmosphere»

Now, scientists at Rensselaer are turning these atmospheric assumptions on their heads with findings that prove the conditions on early Earth were simply not conducive to the formation of this type of atmosphere, but rather to an atmosphere dominated by the more oxygen - rich compounds found within our current atmosphere — including water, carbon dioxide, and sulfur dioxide.

Scientists from the Max Planck Institute for Nuclear Physics have now discovered that plants themselves produce methane and emit it into the atmosphere, even in completely normal, oxygen - rich surroundings.
