I think you're right, nprev. We don't see the atmospheric pressure at the top of Mt Everest being any higher than at any other equal altitude on Earth (though this may be a bad example due to the high mass of the planet).
Also, just to throw this in, Mercury has a non-spherical exosphere due to stellar wind effects. -------------------- -- Hungry4info (Sirius_Alpha)

I think you're right, nprev. We don't see the atmospheric pressure at the top of Mt Everest being any higher than at any other equal altitude on Earth (though this may be a bad example due to the high mass of the planet). The air pressure tends to be substantially lower at the poles, even at the same altitude. For example, the summit of Denali (at about 6.2 km) has an air pressure equivalent to that at 6.9km altitude in the Himalayas (say Everest). |
