What is the specific volume of the entire atmosphere of planet Earth?

Question

[Height of the atmosphere divided by 2] X [Total surface area] ?

I consider the ozone layer to be the top of the atmosphere.

Answer 1

A little over 17 and a quarter trillion cubic kilometres.

The atmosphere extends to the far reaches of the exosphere which is 10,000km above the earth.

Ignoring the volume occupied by Earth for the time being...

The diameter of the exosphere is therefore 10,000 + 10,000 + 12720 (diameter of the earth) = 32720km. The radius is therefore 16360km.

The volume is four thirds multipled by pi multiplied by the radius cubed (4/3 π 16360³) = 18,341,650,640,000 km³

Less the volume of Earth occupied by Earth. (4/3 π 6360³) = 1,077,605,665,000km³

18,341,650,640,000 - 1,077,605,665,000 = 17,264,044,985,000km³

Well...i believe everyone else pretty solved the problem for you.We' re talking about a planets ATMOSPHERE here.To change the gaseous composition of a bell jar is one thing;to completely alter several thousand tonnes of gas(if any atmosphere is even present in the first place),is a bit harder. Lets go planet by planet. Mercury is too hot to even consider inhabiting,but lets assume that some of us want a really quick suntan.Mercury's position near the sun means its atmosphere is constantly blasted away by solar winds.So an atmosphere is almost impossible to maintain. Venus is basically Earth 200 years from now if our current politicians dont do something about the environment soon.The best way to tackle this would be to use lithoautoprophs,like some bacteria(tough little critters that would just LOVE venus)to suck up that sulphur and turn it into carbon dioxide.From there,algae plants can do the rest in about 10000 years to change the atmosphere to Earths atmosphere. Earth:DUH,the usual,stop polluting!!! Mars:Most likely to be inhabited.Just melt those solid carbon dioxide caps at the equator and siphon the result to those good old algae.With luck you can breathe Martian air in a few thousand-ten thousand years(depending on how many plants you use) Jupiter:Well,interestingly the atmosphere has the beginnings of primordial soup at 20ppm,which means you'll have better luck starting life off on the Sun.So,all you need to do is send a REALLY huge tank of oxygen there and light a fuse.You'll get a lot of water from the 90% hydrogen in the air.Then do the same as the prevous planets. Saturn to Pluto:Get a really big hairdryer and warm them up.All the things needed are actually crystallised on the surface/in the air.And keep the planet warm or else all those gases will solidify again.

Volume Of The Atmosphere

Answer 4

RE:

Answer 5

There is no "specific" answer because of the difficulty in quantifying the thickness of the Earth's atmosphere (see http://www.pdas.com/atmthick.htm ). Volume involves knowing certain spatial quantities.

But, if you want o use the upper limits of the thickness of the atmosphere (100km), then you can find "an answer".

Simple Volume formula: 4/3*pi*r^3

Take the mean radius of earth = 6370.9987 km
End up with roughly = 1014991035148.5156 cubic km

Do the same for the earth plus the atmosphere (add an extra 100km) and you get roughly = 1064966254007.9085 cubic km

Simple subtraction:
1064966254007.9085 - 1016366026179.0716 = 48600227828.8369 cubic km

Voila - hope that answers your question

Answer 6

depends on how you want to define the volume....

Do you want to go by total cubic feet of gas at "standard pressure and temperature"

Or the volume it actually takes up between the surface and as far up as its detectable?

The latter is easier to calculate...

Volume of atmosphere = volume of the sphere with a radius equal to radius of the earth plus thickness of the atmosphere, minus the volume occupied by the sphere of the earth.
(close enough.. both are really ellipsoids, not spheres)

Now look up the diameter of the earth and the thickness of the atmosphere... plug some numbers into a calculator and you have an answer.

Answer 7

The Gasconni - We cannot go to the giant gas planets such as Saturn, Jupiter and Uranus, however, we can probably go to the captured satellite moons of these gas giants, of which there are about 165 moons. For example, Ganymede, Io, Callisto and Europa are the 4 Galilean satellites of Jupiter. Callisto is way too active volcanically and not habitable. Phytoplankton produce about 70% to 80% of the oxygen on Earth, so we could fill a crater up with water, add some phytoplankton and iron sulfate, let the sun heat it up and through photosynthesis it will produce cloud condensation nuclei (CCN). Phytoplankton have a complex effect on cloud formation via the release of substances such as dimethyl sulfide (DMS) that are converted to sulfate aerosols in the atmosphere, providing cloud condensation nuclei. Water vapor clings to CCN's and dust to form clouds. Chemists would react acids with mineral rocks to release various gases. Methane is also a very effective greenhouse gas to warm up the atmosphere and nitrogen can be fixed by growing legumes/beans and from nitrogenous waste.

Answer 8

That's a tough question, there seems to be a debate as too just how far out our atmosphere extends. I am anxious to see what others say the answer is to this question. Keep us thinking Ultramatem.

Answer 9

I agree with Hugh Jafro (is your brother's name Lar).

It all depends on what you consider atmosphere.
