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.

21%
The percentage of oxygen in the atmosphere does not change with altitude, so it is about 21% at 10 000 feet. What does change is the pressure. This declines with altitude. At sea level the air pressure is about 101 kPa (kilopascals). Oxygen accounts for 21% of this so the oxygen pressure is 19.6 kPa. This means that there are less oxygen molecules in the same volume of air at higher altitudes. At 10000 feet the oxygen pressure drops to 7.2 kPa, which is roughly one third of the pressure at sea level. For an online calculator of oxygen levels at different altitudes see: http://www.altitude.org/calculators/oxygencalculator/oxygencalculator.htm This site also lets you convert between kilopascals and mm Hg.

The earth's atmosphere at sea level.
The atmosphere is composed of approximately 21% oxygen by volume. The remaining components include nitrogen (about 78%) and trace gases, including carbon dioxide and argon. This percentage can vary slightly depending on altitude and environmental conditions, but it remains relatively constant at sea level.
Sea level oxygen is around 21% and Denver has about 18% available oxygen.

At sea level everywhere on the Earth oxygen makes up about 20% of the atmosphere.
Yes, there is a difference. The percentage of oxygen at sea level is around 21%, while at the summit of Mount Everest it is about 33% lower due to the extreme altitude. This lower oxygen level makes it difficult for climbers to breathe and can lead to altitude sickness.
At the top of Mount Everest, the percentage of oxygen in the air is the same as that at sea level (about 21% oxygen). However, atmospheric pressure decreases as altitude increases, and the atmospheric pressure at the summit of Everest is 33% that of sea level.Therefore, there is 66% less oxygen than there is at sea level.
At the summit of Mount Everest there is approximately 33% of the oxygen that is available at sea level.
The percentage of oxygen at sea level is approximately 21%. This level remains fairly consistent with slight variations depending on location and other factors.
There is more oxygen available above sea level as the air gets thinner with increasing altitude, leading to lower oxygen levels. Below sea level, such as in deep-sea environments, the oxygen levels can vary but are generally lower compared to surface levels.

Less oxygen
Standard oxygen concentration for earth's atmosphere is 20.9% Theoretically, this percentage does not change at varying altitudes. What changes is the density of the oxygen (and other gases, such as nitrogen) present in the air. At sea level or on a mountain top, oxygen concentration is 20.9% However, depending on things like air pollution and location (indoors vs. outdoors), O2 concentration can vary widely, down to as little as 10% in polluted indoor environments.
