Because the air is thinner and stays colder
that only works in an enclosed area outside it is the opposite with winds and air pressure pushing down the hot air
Goood Question. Lets just ask Mr. Know It All, $mitty!!! Grrr I dilike him... =E
Have you ever seen melting snow run uphill?
i guess for the same reason that it's frigidly cold in outer space..
The air gets thinner the higher you go up.
Because wherever there is snow at the top of the mountain,it does not get hot in that atmosphere, environment.
Air gets lighter as you go up.
Hot air does rise but when it does it cools and condenses. The higher that you go up the colder it gets in the atmosphere. mountains are in cooler parts of the atmosphere. the reason why higher altitudes are colder is because the earth and water store heat. At higher altitudes there is less amounts of water and less amounts of land, therefore there is less heat eminating from these surfaces, thus air does not rise as much. At lower altitudes, the air gets hotter and this hot air rises up. As the air rises up however, it cools and condenses into clouds. When the atmosphere at high altitudes has too much evaporated moisture, it falls as the various forms of precipitation.
At those high altitudes that clouds are at, though, the temperature is very, very cold, so the precipitation falls as snow and ice. This is true everywhere in the world, even in the tropics. The precipitation falls as snow and ice. However, when it falls through the atmosphere, it absorbs heat from the atmosphere as it passes through the warmer, rising air. This melts the ice and snow into rain. On mountains however, it is still very cold, considerably colder than the air at sea level. Ths snow therefore does not melt into rain, but stays and falls as snow collecting for many years. The collected snow then pack and cool the snow above it that falls further dropping the temperature of the air around the mountain causing more snow to fall.
The wind, then also blows the warm air that rises. So the hot air not only rises up but in the direction that the wind blows. The wind then blow the warmer, moist air until it reaches a higher land mass, a mountain , a barrier that impedes its movement. This forces this hot. moist air upwards the mountain and then forces it to condense along the cooler slopes of the mountains, which get colder the higher that you get. The moist, hot air then begins to form clouds lower and then precipitates to rain as it cools and rises. This is why most rivers start at mountains and why the bases of mountains are usually covered by forests. This warm air is still forced upwards the mountain by the wind trying to get to the other side. At a certain height on the mountain, it is too cold for rain to fall and snow falls on the slopes then.
Snow stays on mountains all year long because snow also reflects a lot of the sunlight hitting the mountain causing the air to be colder than normal and that causes slower than average melting.
i hope i was clear in this explanation
cause it's pretty
