Asked by caleb
What happens to air pressure as you ascend to higher altitudes?
Air pressure decreases because there is less air mass exerting pressure from above.
Air pressure varies unpredictably, solely influenced by current weather patterns.
Air pressure stays the same, as altitude does not affect air molecules.
Air pressure increases, reflecting higher oxygen concentrations at certain altitudes.

Air pressure decreases because there is less air mass exerting pressure from above.
As you go higher, there are fewer air molecules overhead, so the weight of the column of air (and thus the pressure) drops — roughly exponentially with altitude.
