Question

Why the amount of oxygen is less at very high altitude?

Answer 1

Answer:

The “thin” air at high altitudes has considerably less oxygen and pressure. This is because the earth's gravity holds the oxygen close to the surface — so much so that half of the oxygen in the atmosphere is found below 18,000 feet.

Answer 2

As the pressure decreases at the high altitudes.Oxygen levels depends upon pressure according to PV=nRT,n is the no.of moles of that gas.For example-Pressure cooker,because pressure cooker doesn't work properly at the altitudes,as the name says that it need pressure if there no pressure then how does the pressure cooker work properly at the altitudes.
