if life hadn't arose?

 

I was thinking about it earlier, does anyone have any ideas?

 

A warmer, wetter version of Mars with a really poisonous ocean?

 

Any suggestions for further reading would be welcomed.

Hmm...perhaps Earth looks like what it was when it was just formed after the Big Bang. You know, the hot rocks, lava, and stuff. haha...my imagination is rather limited.

Probably a whole lot cleaner.... and the atmosphere would have more 'exotic gasses' in it. humans and cows wouldnt be here to fart and bring up the methane levels of the astmosphere.

Would there be any carbon dioxide in the air?

Or... which gas was it that became much more prevalent when primitive life flourished in the oceans?

I'd think there would be tons of CO2 in the air, snce there wouldnt be any plants to turn it into oxygen... if Im wrong, tell me. I havent taken chem class since the 7th grade- but im starting again this year.

Weren't the first life-forms ones that used carbon dioxide in an atnosphere of mainly carbon dioxide? They eventually used it all up "polluting" all there air with oxygen.

 

Hmmm, maybe it's not ever really "pollution" at all, just a change in ratio of gases... weird thought.

Yes it's oxygen that they released. Started during the Orosirian period? From cyanobacteria.

And most of them ended up dying from oxygen poisoning, as you say.

There wouldn't be any oxygen in the atmosphere.

What about Nitrogen? Would there be any nitrogen in the air, if nothing was here?

Would there be an Earth (or universe for that matter) if we weren't here to observe it?

would it be poisonous if there is no life? i mean, what is there that it would poison?

Every time you look at Venus and Mars you can see what earth would look like without life. Venus and Earth were at one time in the same orbit (Opposite sides) and Mars once occupied the space where earth is now.
