What happens to the pressure and temperature as you go up in the entire atmosphere?

Answer 1

As previous contributors say, pressure goes down with altitude. The higher you go the lower the pressure. Low orbit satellites (about 500 miles up) run about as low as you can get without serious friction from the atmosphere. They still require some boost over time because there's still a trace of atmosphere even that high.

Temperature is a bit more complex. It starts out falling at about 3F per 1000 feet (see Wikipedia reference) but in the stratosphere it increases then above that it decreases then it increases again (see nasa reference).

Oh and by the way it's about 15lb/sq in pressure at the surface, not 29 (I think he was referring to inches of mercury:)

Answer 2

The pressure always decreases with height throughout the atmosphere but the temperature value fluctuates with height. The temperature decreaes in the troposphere with height as the lower atmosphere is heated below by the terrestial radiation and starts increasing in the next layer of stratophere mainly due to absorption of Ultra-violet rays by the ozone layer.This trend continues till we reach a height of 60 Km.Above this height, the temperature again falls in the Mesosphere and become minimum ( about( --90 degree celcius)at a height of 80 Kms. Finally,the temperature starts increasing indifinitely in the next layer of the atmosphere called thermosphere.
The atmosphere between 30 to 80 Kms is sometimes called ozonosphere and above that Ionosphere where the atoms and molecules of nitrogen and oxygen become progressively ionised and the temperature increases here with height.Above this layer comes the outer most layer of the atmosphere called exosphere .In this layer also the temperature continues to increase with height.

Answer 3

The weight of air at sea level is about 29lbs. That's called barometric pressure, right? Increase altitude and that weight diminishes. (There are weather patterns that cause a small variance, but very little.) Yes, the air has weight. Gravity has pulled it to be the most dense at the surface. At altitude it thins out. It requires mass to hold the suns warmth. The thin air doesn't hold heat well. Snow on the mountains in the middle of summer. OK.

Answer 4

As one goes up the density of air reduces which results in a reduction in pressure. The temperature also reduces as one goes to higher altitudes. It reduces by approximately 1 degree fahrenheit per 1000 feet.
