A thing to think about re: mixing of alcohol and water is that both are
polar molecules, and thus mutually attracted, which no doubt
Another example of a top-of-the-atmosphere special layer is of course the
ozone (O3) layer, continually produced by ultraviolet light but unstable.
These "surface" phenomena don't have anything to do with how nitrogen,
oxygen, and uranium hexafluoride are distributed throughout the atmosphere.

Okay, there are issues of definitions. I'll note that the upper atmosphere
is bombarded by "cosmic rays" which in fact are mostly very high-energy
protons originating outside our Solar System. Protons are of course the
nuclei of hydrogen

Huh? That makes no sense. Moreover, there is NO hydrogen or helium in
our atmosphere. Any that we might have once had is long gone. Given
the very large average height and correspondingly high average speed

Thanks, everybody.
I realize that most of you have day jobs and don't have time to be teachers
in my self-designed Elder-Hostel Education program, but if you do have a
moment, could you answer the following questions?
In these questions, the words "cool" and "warm" will have a technical

I forgot to mention to Nick that planetary atmospheres *do* vary over
