Air seems thinner at high altitudes because air pressure is lower, which allows individual air molecules to occupy a larger volume than air molecules do at low altitudes. This decreasing pressure with increasing altitude occurs because there are increasingly fewer air molecules exerting pressure on the next-lowest altitude.
So although the percentage of oxygen in the atmosphere is the same, the thinner air means there is less oxygen to breathe. Try using our barometric pressure calculator to see how air pressure changes at high altitudes. Or use the altitude oxygen graph to see how much less oxygen is available at any altitude.
“Thin air” does not have less oxygen. The percentage is the same as sea-level air. The air pressure at high altitudes is not lower than the air pressure in your lungs. If this was the case, it would be physically impossible for air movement into the lungs. Lastly, veins do not pump oxygen throughout the body.
The air high up does not have as much air above it, so less weight is pushing down on it to compress it. This results in a lower air pressure, meaning air up high is thinner. This is the same reason why the water pressure is less at the surface of the ocean than at the bottom of the ocean.
The reason it is thinner is because air has the same amounts of oxygen, nitrogen and other gases at all altitudes but as you go higher it is spread over a greater area and continues to be spread ...
Into Thin Air: Weight Loss At High Altitudes. In addition to a lack of oxygen, there may be another reason its called thin air–researchers have been exploring the relationship between weight ...
As the others have mentioned, the air at a certain height is compressed by the air above it. You can imagine a column of air, with its bottom at sea level, rising to the top of the atmosphere. At sea level, the air is being compressed by all of th...
Athletes from many sports have used altitude training to prepare for a big match or event, and not just when the event will be at a high altitude. They do this because the air is "thinner" at high ...
As air rises, the pressure decreases. It is this lower pressure at higher altitudes that causes the temperature to be colder on top of a mountain than at sea level. For more information on related topics, try the links below.
As at higher altitudes the density of air decreases, which means that air is thinner. As a result golf ball travels farther at a higher altitude because of decreased drag on the ball. Load More
