if warm air rises and cold air descend, why are mountain-tops cooler than the lowlands?
Radiation from the sun does not generate heat as it passes through the atmosphere until it hits the earths surface. since air is not a very good conductor of heat, heat is lost with distance away from the earths surface. the mountain top is some distance away from the larger area of the earths surface.
Temperature decreases at the rate of 0.6c per every increase of 100m.
...So it means most heat remains on the near surface as air is a poor conductor of heat. While The minimum heat goes higher n then it cools faster!
Now what about density! Isn't warmer air less dense than cool air? Thus, the warmer air will all be forced to move up n leave the cool air beneath it! Though air is a poor conductor of heat?
do you know anything about diffusion??
did i teach you physics?? you said it correct. ila kwa kuongeza tu as the air rises it does not retain its temperature it adopts the surrounding temp.
thank u 4 ur gud answer! But if air adopts the surrounding temp, it means that it will either lose or increase its initial temp in order 4 it to adopt 2 the new surrrounding, ryt?

It does not adopt its surrounding temperature, it cools because it expands, the act of expansion needs energy so heat energy is used to expand the air thus cooling the air.
