why there is snow on mountain tops though heat travels upwards????

Answer 1

maybe because snow falls downward...and its temperature can resist the heat travelling upward...

Answer 2

The atmosphere is not heated by the direct,short-wave solar radiation and instead is heated from below by the reflected long-wave radiation from the earth's surface. Some of this solar radiation is absorbed by the earth itself,and is coverted into heat.
Part of this heat penetates downward and serves to raise the temperature of the surface.Another part is utilised for evaporation purposes over water surfaces.The remaining part of the heat only is radiated into space,as long-wave radiation.
Even this meagure amount of heat(long-wave radiation) is trapped within the lower layers of the atmosphere(3 to 4 Kms from the surface) by the water vapour and CO2(which are abundant near the surface) resulting what is known as greenhouse effect.Hence the heat escaping to higher layers of the amosphere is very less and becomes nil after certain height.
So,the heat from the surface penetates into the atmosphere only to a small height. As a result,the snow forms over mountain tops.

Answer 3

yes, air is less dense but the amount of carbon is a lot less, carbon absorbs the suns rays and converts to heat, and the carbon particles float through the air and heat what ever they land on or touch, if there was no carbon there would no heat, beleive it or not, but the more carbon you have the warmer it feels, and since carbon is naturally dense it is not able to stay up at a higher elevation, so heat is basically no exsistent in higher elevations.

Answer 4

The air gets thinner the greater the elevation. When the air thins out it looses its ability to trap or hold heat.
