Hello, I'm a newbie so please tell me if I'm doing anything wrong :)
I am working on a portfolio for school and I have chosen the topic "Air". As I was all set and ready to start, I realized that I didn't know the first thing about air. By now I know that what we call "air" is in fact the atmosphere surrounding the earth... and that's as far as wikipedia could help me. But the amount of my remaining questions scrapes infinity, so I would be very thankful if somebody could answer even some of them:
When has this athmosphere started to exist? Was there a time when the Earth existed without an atmosphere around it? Do these gases also exist somewhere outside Earth's atmosphere? If that's the case, could it be that those gases were "pulled down" to earth? Or is it that rather than being pulled down to it, the Earth "emitted" those gases? If so, does the Earth still emit gases (maybe even "new" gases)?
Has the atmosphere changed and is it going to change over the years? If yes, did organisms also change according to the atmosphere? Or did the atmosphere change according to the organisms?
Do other planets have an atmosphere? And, I hardly dare to ask, what about stars, meteors and the like?
Could we, willingly, change or influence the atmosphere and is this bascially what everbody calls global warming?
Thank you in advance :)
(Sorry, if my English seems a bit weird, it's not my mother tongue)
