Wind and liquid currents

[Slightquills]

It always seemed strange to me that air would remain relatively stagnant even when pressurizing a vacuum I have recently excavated. It could help a lot with air flow if wind and liquid currents (flow from high pressure regions to low pressure regions) was much more dramatic. It could help "pull" CO2 over oxyferns or "push" high pressure oxygen into other caverns.

Even if the end result is still the same once everything is pressurized I can see it adding to the drama when building and excavating.

This is due to theirs gas dynamics ->

pressure = mass

and

Some elements goes up (like hydrogen) and others goes down like (CO2). I agree with you, it would be better if we had better gas physics.
