Polar air is denser because it is colder.
because hot air is less dense than cold air therefore when air becomes less dense its air pressure decreases.See the link for more information.http://www.mhhe.com/earthsci/geology/mcc…
Air becomes more or less dense relative to its temperature. Cold air is denser than warm. Since the equatorial region is tropical, the air will be warmer and less dense.
In the mesosphere, the air is more dense.
The Polar Jet Stream, or more generally the Polar Front.
Polar easterlies!
Humid air is more dense.
its has more pressure
air is more dense than helium
Lead is more dense than air.
No it is more dense than hot air
Saturated air is more dense.
No it is more dense than hot air
