Why is the oxygen thinner at higher elevations?

    Yes, oxygen is thinner at higher elevations. This is why mountain climbers sometimes wear oxygen masks when they get closer to the tops of the mountain. There is less oxygen because there is simply less air.

    This is mostly a question of pressure. At sea level, the pressure is stronger than at higher altitudes because we have more atmosphere pressing down on us. Because gases can be compressed, there is a higher concentration of gas molecules under high pressure than at lower pressures. Therefore, the higher you go, the lower the pressure, the less oxygen there will be.
