no it is actually the highest point whcich is above 550 kilometers
No, it ends at an altitude of 80 kilometers
Sea level oxygen is around 21% and Denver has about 18% available oxygen.
In kilometers, the elevation of the South Pole above sea level is 2.8349448.
35,000 feet = 10.668 kilometers (rounded)
5,280 feet is 1.61 kilometers.
200 km above sea level.
well.logically it just makes sense that since there is less oxygen above sea level (mt Everest roughly 1/3 of the oxygen at sea level) that there would be more oxygen below sea level. note: this is completely hypothetical and has no scientific backing whatsoever
the aircontains 20.93% oxygen-whether you are swimming in the Dead Sea in Israel (1,369 feet or 417 meters below sea level) or standing on top of Mount Everest in Nepal (29,035 feet or 8,850 meters above sea level). the barometric pressure is lower the higher in altitude you go so the pressure of oxygen is lower therefore its harder for your lungs to absorb the oxygen.
At sea level everywhere on the Earth oxygen makes up about 20% of the atmosphere.
2.66666666667 is the decimal of oxygen in the air
