pressure drops with a rise in altitude. is the same as being submerged in water. The deeper you go, the greater the pressure and visa versa. air can be looked at as an ocean

8750 metres is called scale height. That means that if you go up 8750 metres, the pressure will be about what it is here divided by 2.71828. Or put another way, for every 15000 feet you go up, air pressure approximately halves. So if you go up 30000 feet the air pressure is about a quarter of what it is down here. That's a little bit higher than Everest. These are only approximate; the rate at which air pressure decreases with height depends on the air temperature, and that changes all the time.

complicated. If the temperature of the air have been uniform, the stress could decrease logarithmically with altitude. notwithstanding this isn't any longer -- it decreases with the help of roughly 2 C in line with thousand ft improve in altitude. in case you grind out the maths (this is a rather user-friendly critical calculus difficulty), you detect that the stress decreases at some thing like the -4.25 power of the altitude. this is powerful as much as slightly over 30,000 ft; at that factor, you're interior the stratosphere and the temperature will become almost consistent with increasing altitude, so the stress decline is logarithmic. The tension is approximately 0.5 of sea point tension at 18,000 ft, and 1 / 4 at 40-one,000 ft. you will detect tables and graphs of this in:

Air pressure is the weight of air. The closer to the Earth, the more air is above it. Therefore the closer to Earth, the heavier it is. The higher you go above sea level, the less dense, the lighter the air is

They're inversely related. That is, as altitude increases, air pressure decreases.

This is called indirect, or inverse, proportion. As one number gets larger, the other gets smaller. At greater altitudes, air pressure gets smaller.

Air pressure is the weight of all the atmosphere above you. As you go up there is less air above you so less weight or air pressure.
