If heat RISES WHY IS THERE SNOW ON MOUNTAIN TOPS?

Yes, heat does rise. But, it expands into lower pressure and undergoes what is called 'adiabatic cooling', just like a spray can feels cold when you release pressure. Dry air cools 5.4'F for every 1,000 feet it rises. Thats more than 20'F of cooling for a 4,000 foot mountain, enoough to bring snow.  Cold air warms as it sinks for the same reason, which can create perfect winter days.\n\nI hope this helps! Let me know!

It takes time to transfer the thermal energy to the snow.  Snow also has an insulating effect on lower layers of snow, making it difficult to transfer heat there, making snow more persistent than would be expected.

Because the air spreads out, and as it spreads out it retains less heat.\n\nAnd while cold air does sink and hot air rises, as cold air does get lower in altitude it warms up, and hot air cools as it rises. \n\nI live in the foothills west of Denver so I see the rising/falling air thing firsthand. In the winter we get this air that 50 miles to the west was part of a blizzard. As it descends the mountains, it dries out and heats up sometimes bringing temperatures in the middle of the winter into the 60's or 70's.

The simplest answer I can give you is that the air doesn't absorb much heat from the sun (sunlight passes through it), while the ground does (the exception is ozone, which does absorb more radiation, and thus higher up in the atmosphere, there is actually a warm layer).  So the ground is actually what is doing the heating, and the higher you go in the atmosphere, the further you are from the ground, the cooler the temperatures.\nOf course mountains are ground... but air at the same height mixes about quite a lot, so while air near a mountain might be a bit warmer... the air in other places at the same height is well above the ground, so it's cooler overall.\n\nIn addition, air cools as rises, a second reason why its cooler higher up in the troposphere.\n\n\nSpace is really really really cold!  It's for the same reason.  The light from the sun itself isn't hot... it's when its absorbed by something, which heats it up.\n\nHope this makes sense, let me know if there is anymore I can help with here,\nGod bless,\nShane

Temps close to the freezing point. If you have noticed often when rain is changing to snow quickly,the flakes at times are huge!

While it is true that hot air rises, it is also true that it will cool as it rises. This is called adiabatic cooling.\n\nAir pressure deminishes as you go to higher altitudes b/c there is less gravity. Less air pressure means air particles are more spread out. Hence the adiabatic cooling effect.\n\nThis is true in the troposphere, the atmospheric layer in which we live & where weather occurs.\n\nAs you go higher the reverse happens. In the stratosphere it gets warmer due to the ozone layer. In the mesosphere it gets colder again b/c you move away from the ozone layer. In the thermosphere it gets warmer again b/c of the bombardment of air particles by intense short wave solar radiation.

The warm air pushes the moisture higher into the colder air layers....as the moisture droplets freeze together  they fall and enter the warm air currents which pushes them back up to the cold layers..this happens until enough layers are built up, that the updrafts can't support the weight and the ice falls to the ground in the form of hailstones.

Heat likes to rise. If there are clounds, they keep the heat in. On clear nights, the heat can rise up and away and it gets colder.

because on the mountains the air is more thin...duhh

the gases build up that pushes the molten up, if there is snow causes hazardous and gaseous mud slide down the mountain.  Causes some tremors like earthquakes. Hazardous smoke (ash) cloud.  look up mount saint helens in Washington or the volcanoes in hawaii.  plus there are many throughout south america.  Pictures of mt. st. helens are awesome. I went there after it happened in 1980 it was phenomenal!  I felt the tremors up by bellingham. it was cool.

rising heat under that type of cloud causes thermal updraft which gives better lift to the bird

Maybe the ground temperature is hotter. Its temperature doesn't count on outside factor. The sun is just 1 factor.

Because the air is less dense the higher the altitude, there are less molecules available to retain heat. Therefore the heat of the sun dissipates more readily.

That is a fantastic question.\nIt is a matter of humidity. The cold weather\nthat allows snow means the air is not humid\nenough to allow an electric current to travel\n(along the water vapor in the air) over the differently\ncharged clouds and sky. People who say temp are\nsort of right, but it is the low temp that leads to the low\nhumidity that causes the "problem".\n\nThanks for asking such a good question.

High winds travel up the roof following the contour of the roof line and a low pressure area is generated at the roof's peak. This phenomena causes the roof to lift off.

Mountains are higher in altitude than the plains.\n\nThe higher you go, the less atmospheric gases there are. This is due to the fact that gravity holds these gases close to the surface.\n\nAir holds heat. If you have less air then there will be less heat.\n\n:)

Moisture..\n\nWind is wind... It's the wind chill factor and depends upon moisture on your body or moisture in the air.\n\nThe moisture either on your body or blown onto your body will be evaporated by your body. This uses up a lot of energy in the form of heat.\n\nMountains..\n\nIf mountains are near you and you are getting wind from the mountain range, chances are this wind will be hot and dry.. The wind hitting the other side of the mountains will loose all its moisture in preciptiation as the air rises and cools quickly causing the rain.. The wind coming from the mountains will be dry and warm.\n\n\nBlowing towards the mountains, the wind will be moist and back up to the top...
