If the airplane's cabin is not "pressurized" then it will have low atmospheric pressure. That means the air is thinner. The air is less dense. The molecules in the air are farther apart. At lower altitudes the air is compressed and made denser since the molecules are shoved closer together, and you get more of them in each lung full you breathe. If you blow up a balloon on the ground and then take it 10,000 feet in the air, the air trapped inside the balloon will expand because it wants to match the density of the air around it, and air is less dense the higher up in the atmosphere you go.
P.S. This is why pilots of non-pressurized airplanes wear oxygen masks when they fly high. The air above 10,000 (or 14,000, or something like that) has too few molecules of oxygen for each lungful of air you suck in.

Is the pressure high or low at high altitude?
it is low. due to gravity
What is healthier - living at low or high altitude?
High altitude
How would the observed temperature be affected if distillation was performed on top of a mountain?
The boiling point temperature is lower at low pressure (altitude).
Does it move from an area of high pressure to low pressure or low pressure to high pressure?
A fluid will move from high pressure to low pressure.
Does a satellite in low tilt at low altitude show more of the earths surface than one in high tilt at same altitude?
a satellite in a low tilt at a low altitude can see earth better.
What defines low air pressure and where is low air pressure typically found?
There is low air pressure usually when you are up in a mountain or in an airplane like when your ears pop after you get in an airplane and you are at high altitude your ears do this because the pressure inside your ears and the pressure in the air is not the same. When there low air pressure the air is less dense.
Is the pressure high or low at high altitude?
it is low. due to gravity
Can air pressure falls drastically at high altitude?
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.
Why do nose bleed at high altitude?
because the pressure is high and temperature is low
Why Nose bleeds at high altitude?
because the pressure is high and temperature is low
How does atmospheric parameters affect aircraft's lift and drag force generation while gaining altitude?
Temperature - low temperature gains altitude quicker Pressure - High pressure gains altitude quicker Density - Low density gains altitude quicker
Is the air pressure in a flying airplane greater that outside the flying airplane?
In a commercial airliner flying at cruising altitude, the air pressure inside the airplane is considerably higher than the air pressure outside. The air pressure outside is too low for people to breathe comfortably, so the interior is pressurized.
Is air pressure greater at high altitudes or low altitudes?
It is greater at a lower altitude.
What is healthier - living at low or high altitude?
High altitude
How did the Nazis do their high altitude experiments?
They used low pressure chambers that could simulate altitudes of 66,000 feet
How airplane flies?
differential in wind speed over the wings produces high pressure under the wing and low pressure on top of the wing.
Why is the boiling point in Durban different from that in Johannesburg?
Boiling point is dependent on air pressure. Air pressure is dependent on altitude. Durban is coastal, almost sea level. Johannesburg is inland, quite a bit higher. High altitude = low air pressure = low boiling point.
