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.

∙ 14y agoThe earth's early atmosphere was made up of 98% carbon dioxide with some water vapour, ammonia and methane.
- The water vapour condensed to form oceans
- Plants intook CO2 to produce O2 by photosynthesis
- Some of the Carbon Dioxide also dissolved in oceans (form insoluable rocks)
- Denitrifying bacteria produced nitrogen gas
- Methane and Ammonia reacted with Oxygen in atmosphere
- Levels of CO2 were slowly rising due to burning of fossil fuels

How was the early atmosphere different from your atmosphere?
well sir, you see balls are very harry. that is all.
Why did the early atmosphere change?
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.
The gases in Earth's early atmosphere came from what?
Volcanic eruptions
What gas was missing from earth's early atmosphere?
probably oxgen
How did the atmosphere on Mars form?
The majority of the atmosphere of Mars resulted from the outgassing of the planet's interior. This occurred very early in its formation.
What did the early atmosphere contain?
EARLY ATMOSPHERE have humidity
If you can travel to a planet with an atmosphere like that of early earth would you be able to survive?
no
What were the conditions like on the early Earth?
The surface of early earth was mostly molten and volcanic. The atmosphere was hot and highly toxic.
What happened to the water vapour that was in the early atmosphere?
What happened to all the water vapour in the early atmosphere
How was the early atmosphere diffrient from our current atmosphere?
pollution
What was the early atmosphere of earth like?
Unbreathable. Lots of CO2 and methane and hydrogen & no oxygen. Nitrogen was about the same.
What gases were there in the early atmosphere?
Oxygen
What gas was lacking from earths early atmosphere in the early precambrian?
oxygen
How did the primitive atmosphere differ from atmosphere today?
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.

Was there oxygen in the atmosphere of early earth?
No! Stromatolites converted the toxic atmosphere into a breathable one.
