The phenomenon of air rising is simply the way pressure is affected by temperature, creating what are called convection currents in small spaces (such as a house). The reason it becomes colder as altitude increases is because of a decrease in pressure due to the atmosphere being thinner and gas molecules being more spread apart. Because they are more spaced apart, they collide less, and collisions cause heat, therefore less pressure means less heat... which is why it's colder.

Cause it only stays warm until it comes into contact with, and mixes with, much colder air higher up. I'm just a dumb blonde but can work that out myself. Where does that leave you darling?

THE AVERAGE TEMPERATURE DROP IS 5.4 DEGREES PER 1000 FEET. WARMED AIR DOES RISE BUT ONLY UNTIL IT COOLS AND THEN IT REVERSES DIRECTION BUT THE HIGHER YOU GO IN THE TROPOSPHERE (UP TO 36000 FEET)THE COLDER IT GETS DUE TO THINNING OF THE AIR.
