Oxygen levels in the oceans and atmosphere increased enough that many new life forms
evolved. They could use oxygen directly from the ocean and atmosphere.
Correct AnswerCyanobacteria (microscopic organisms) developed in Earth's oceans as Earth's
first photosynthetic organisms - releasing oxygen into the atmosphere. The amount of oxygen in
the atmosphere reached one percent of today's levels (so about 2% as compared to 21% of air
today).
Correct!
1 (earliest atmosphere)
As Earth cooled early on, its atmosphere was influenced primarily by volcanoes. It included
mostly hydrogen, sulfide, methane and LOTS of carbon dioxide.
