Gravity doesn’t compress air??
JC did you hack Cricks account to make him sound ridiculous
In the Earth's atmosphere, Frank, what is the difference between the total mass of all air descending to lower levels with greater pressure and density - and the total mass of all air ascending to higher levels with lower pressure and density?
The DIFFERENCE Frank. I'm fully aware that air moves up and down in the atmosphere. You seem, though, to be unable to take a step back and see that atmosphere as a whole is neither expanding away from the Earth's surface nor squishing down towards it. There is NO NET vertical motion of the atmosphere as a whole.
Work done by air masses rising and sinking come in opposite signs and negate each other. The net total of work done by gravity on the atmosphere, therefore, is ZERO.
I'm betting you fall into that intellectual gray area where you're smart enough to see that what I'm saying is correct but too stupid to see the value in admitting it.
