That depends upon which Epoch. There have been four mass extinctions [over several hundreds of million Years] caused by Earth being over run by Cyano-[Purple]-bacteria; these onslaughts were caused by highly irregular Atmospheric Conditions.
The earth's early atmosphere was made up of 98% carbon dioxide with some water vapour, ammonia and methane.
Earth's atmosphere is mostly nitrogen, about 78% by volume, with oxygen about 21%, and argon and other gases about 1%.
nitrogen, water vapor, carbon dioxide and ammonia
Nitrogen, oxygen and carbon dioxide probably made up Earth's early atmosphere.
No
well sir, you see balls are very harry. that is all.
deu to change of state of environment wheather of that atmosphere, evaporation is high and such bring about rainfall and the cloud of that atmosphere changes.
probably oxgen
Volcanic eruptions
The majority of the atmosphere of Mars resulted from the outgassing of the planet's interior. This occurred very early in its formation.
EARLY ATMOSPHERE have humidity
no
The surface of early earth was mostly molten and volcanic. The atmosphere was hot and highly toxic.
What happened to all the water vapour in the early atmosphere
pollution
Unbreathable. Lots of CO2 and methane and hydrogen & no oxygen. Nitrogen was about the same.
Oxygen
oxygen
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.

No! Stromatolites converted the toxic atmosphere into a breathable one.
