My 8 year old asked what would happen if you take the atmosphere clone it and put it at the edge of our current atmosphere.

My 8 year old asked what would happen if you take the atmosphere clone it and put it at the edge of our current atmosphere. And I find that insanely nerd and need #scientist help. I'd assume earth's gravity would pull the new atmosphere in and thus making the pressure go up. But how much? What else?

#physics #physicists #physicist@ozoned The pressure at the surface would double, since pressure is provided by the accumulated weight of the atmosphere pushing from above. Two atmospheres, two times the pressure.
The depth of the atmosphere wouldn't change much though (depending on where you start measuring it) because air is highly compressible.

@jsbarretto that is awesome. Thank you!

#physics #physicists #physicist@ozoned I have to respectfully disagree with the other reply. The edge of earth's atmosphere represents the point at which gravity is not strong enough to retain gaseous molecules. In particular, there is no helium in the atmosphere because it is too light to be retained by earth's gravity. Available gravity also explains why Mars does not have much of an atmosphere. A second atmosphere around earth would simply escape into space without enough gravity to keep it in place.

@paulmasson oh! I love it! Excellent point.
