Consider the way a refrigerator works: a gas (refrigerant) is compressed and it gets hot, this passes through the hot coils at the back of the fridge to cool down. The cool compressed gas is then allowed to expand suddenly through a nozzle in the freezer, and the gas gets very cold, which makes the freezer cold. The gas then returns to the compressor for re-compression and completes the cycle.
Assume you had an insulated floppy balloon of air (as in a gondola balloon) at sea level at 20 degrees centigrade, at the same pressure as the surrounding air. You then carry the big floppy balloon to the top of Everest. The air pressure in the atmosphere decreases the higher you go up because less air is pushing down on you the higher you go up. Because the air pressure is lower, and the air in the balloon expands (it was a very floppy gondola balloon, and can expand freely). As we saw with the refrigerator, when a gas expands, it gets cold! Hence the air in the balloon will be much colder than at sea level, as is all the air around it.

The high altitudes cause it to be colder.
No, though higher altitudes will be at the freezing point more often.
The air gets colder at high altitudes. Sunlight warms the ground, and high altitudes are farther from that warmth.
Colder climates in higher altitudes.
At higher altitudes it is colder. The cooler air can't hold the water in gas form so it condenses out as clouds.
The density of air is less in higher altitudes. Since the dust particles in the air absorbs the light ,we feel heat .
NO!!!! t5he higher you got the colder it gets, so it preserves the milk
As you move higher into the atmosphere, the temperature gets colder and colder. At some point it is hard to breath and if you're up there to high, you need to come down for oxygen.
just high altitudes
It is cold at very high elevations. Most rain originates as snow at high elevation, which then melts before reaching the ground.
One difference n the life style of people living in high altitudes instead of low altitudes is weight. People living in high altitudes are typically not over weight. They also have less heart disease
Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.
Because it's cold up there. The atmosphere gets colder at high altitudes so the snow doesn't melt as quickly as lower altitudes. But why is it colder? Because the atmosphere is less dense than at sea level. This explains why the air is colder. But why is the GROUND colder? I presume because at sea level, there is an equilibrium (approx) maintained between the ground and the air, while higher up, the air is less dense and so the sun's radiation that arrives to the ground (mountain) is absorbed by the Earth and that ground remains cold enough to support snow. Is this correct, anyone?
Due to higher altitudes temperature decreases, so only we feel colder in mountains than low lands
Your ears will pop at high altitudes because of changes in pressure. As you reach higher altitudes the pressure drops and the changes cause "pops" in your ears.
Cirrocumulus cloud is a clous that often appears at high altitudes.
It is greater at a lower altitude.
The temperature is low at high altitude because air becomes thin when it reaches top. heavier air holds more moisture and makes it thick and allows it not to go to the top. Hence the fall in temperature at high altitudes and rise in low altitudes. As air rises, the pressure decreases. The less pressure there is, the colder the air is(P proportional to T-gay lussacs law). This causes a tire to get hotter when you pump air into it, and a spray can to get colder when you release the contents into the air.
The top of a mountain is closer to the sun than the land around during the day it, but given that the sun is more than 90 million miles away, that difference is negligible. The higher you go up in the atmosphere, the colder it gets. This is because the air at high altitudes is less compressed than the air at low altitudes. When a gas is decompressed, it cools.
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.
i dont know the answer
At higher altitudes the atmospheric pressure is less when compared to that of plains. The lower atmospheric pressure results in lower boiling point of water at high altitudes.
High altitudes do cause drowsiness because there is less oxygen in the air, so you can't breathe normally.
