Why does it snow on mountaines?
At high altitudes, the air is very cold. So, in high mountains, any precipitation will fall as snow.
Why will countries at high altitudes sometimes have cooler climates?
If they are in mountainous areas like the alps, yes. the higher it is the cooler the air
Why do mountaineers carry oxygen cylinders?
At extreme altitudes, the air becomes rarefied and has a very low oxygen concentration. This can lead to a condition known as hypoxia, which is deprivation of oxygen to the brain, which can cause loss of consciousness, paralysis, and death.
How can people in good shape have trouble breathing at high altitudes?
There is less oxygen in the air at higher altitudes. The atmosphere is held in place by the force of gravity, and it is thicker at the bottom, and gradually becomes thinner the higher you go. If you get high enough, the air runs out completely and you are then in outer space. Better wear your spacesuit!
Why doesn't cold air in high altitude sink?
The air at high altitudes is colder that that at lower altitudes, but it is less dense because it is under lower pressure. If you were to force high altitude air down to ground level it would compress and heat up, in most cases becoming warmer than the surrounding air. In such a situation the atmosphere is said to be unstable. In some cases, however, a sinking mass of air might not become warmer than the surroundings. In such cases warm air rises and cool air sinks in a process called convection.
Why do they pressurize airplanes?
Well a simple answer would be that if a plane is not pressurized, on high altitudes or just very high in the sky, the plane will expand like a balloon and if it expands to much, big problems happen and I don't really know how it is pressurized but the air inside the plane is usually very different than the air outside the plane, at high altitudes.
What might limit how high a hot air balloon get?
The density of hot air is lower than air at low altitudes, but the air at higher altitudes is very thin. A hot air balloon can only rise until its density equals the surrounding air.

Why does it snow on mountaines?
At high altitudes, the air is very cold. So, in high mountains, any precipitation will fall as snow.
Why is it very difficult for hot air balloons to attain very high altitudes?
Eventually the air outside becomes thinner than the air in the balloon, so it can no longer float
Is air pressure greater at high altitudes or low altitudes?
It is greater at a lower altitude.
What are high-altitudes high velocity rivers of air are called?
Jet streams
What are cabins with normal air pressure at high altitudes?
high altitude chambers
Do high altitudes cause drowsiness?
High altitudes do cause drowsiness because there is less oxygen in the air, so you can't breathe normally.
Why will countries at high altitudes sometimes have cooler climates?
If they are in mountainous areas like the alps, yes. the higher it is the cooler the air
Why wouldn't you climb mount Everest with a helicopter?
Helecopters (like most aircraft) have an upper ceiling that restricts how high they can go. This is because a helecopter flies by pushing the air around it downward, and the air at very high altitudes (like Mt. Everest) is very thin (reducing the amound a helecopter can push downward). Because Mt. Everest is so high, no helecopter can climb as high as the top of it.
Why is Kilimanjaro is capped with snow?
Mt. Kilimanjaro is very high. At high altitudes, it gets colder. That is because sunlight warms the ground which warms the air, so air that is very far from the ground tends to be cold. At when it is cold enough, you get snow.
