The closer you are to the edge of the atmosphere, the denser air gets. That's why mountain climbers find it difficult to breathe, as there is less oxygen in the air up there.
Because the air is thinner up there. There is less oxygen in the air, so it is harder to breathe.
It decreases because as you move up in altitude the air becomes thinner making it colder.
because of the density of the air and the pressure
the atmosphere isn't more dense. if the atmosphere was on the ground, we would have no air. but the reason the air is thinner in the mountains like mt. Everest and Kilimanjaro is because its further away from the earth center and the gravity has less effect on the air. the closer to the earth center the stronger gravity, the denser air.
The air at the top of the mountain is less dense, meaning there are less particles of oxygen in a certain are than on the ground. It is harder to breathe because the air is so thin, there is not enough oxygen to breathe normally until you get used to it.
The higher you are in the atmosphere, the lower the air pressure. Seeing that the top of a mountain is quite high, the air pressure is low; the air is thinner. This is why you need oxygen tanks to reach the top of Mount Everest
well air is thinner at higher elevations so i would say less at the top...
Air is thinner. So until you are used to it -it feels difficult
the air on the top of the mountain is more thinner because there is less pressure compared to what is going on, on sea level
The air at the top of the mountain is thinner than the air at the base of the mountain. That is why you are harder breathing on the top than on the bottom.The gases are about the same, but there is usually a lot less water vapor (because its cold) :but the pressure is less (that is, the number of molecules per cubic foot is less), down to the point that on top of the tallest mountains humans can not survive for any appreciable time.
aaarrrggg, i know this one. its something to do with the air being thinner
At higher altitudes, the air becomes thinner. Since there are fewer molecules, the air has a lower total kinetic energy, which means the temperature is lower.
The air is usually very thin at the top of a mountain.
As hot air rises, there is less pressure pushing down on it. As a result, the rising air expands. This causes the air to cool. Thinner air + lower pressure = colder conditions. Water vapors in the air then turn to ice (snow) as the it meets the colder air and falls upon the mountain top
The air gets thinner. That's why if you are climbing a mountain the trees are shorter as you get to the top because they don't have as much air as the lower atmosphere.
Air is denser at lower altitudes and less dense at higher altitudes. If the bottom of the valley is directly below the mountain, at a lower altitude, then there is technically more air in the valley.
The air is thinner
