A+ Meteorology :D
we would die
Yes, 80% of the Earths atmosphere is made up of nitrogen.
No we don't get squished when we are leaving the earths atmosphere so neither would a bug
youll die
There is good ozone and then there is bad ozone. Good ozone is present in the earth's atmosphere.
The Earths surface would be much colder than it is.
Nitrogen makes up approximately 78% of Earth's atmosphere.
No. If a comet were to strike the Earth, the results would probably be catastrophic.
It will remain as reductive atmosphere. Ther will be only gases like NH3, H2 , H2S. H2O. There would be no life
If the moon "had" or had had in the past an atmosphere, its gravitational force (about one sixth that of earths) would not have been strong enough for it to stop the gases dissipating into space.
We would not exsist, because it would be too hot. Also, the earth would be a burnt piece of rock.
The earths atmosphere is denser than the helium found in a baloon therefore the baloon is lighter and is lifted above the denser air located in earths atmosphere. Which is why if you just blow up a baloon with air from your lungs it does not float. It would be the same density as the air outside of the baloon.
