Web7 apr. 2024 · Barometric pressure is the weight of the atmosphere pressing down on the Earth. Since the pressure depends upon the depth of the atmosphere above the point where you're measuring the pressure, the pressure decreases as you go higher. WebFor example, the amount of oxygen (O 2) in the atmosphere, assuming there is no water vapor in the atmosphere, is 0.2095 kPa O 2 per kPa air or 20.95%. The atmospheric concentration of O 2 has remained constant for several hundred years at 20.95%. The percentage is the same at sea level or on Mount Everest.
