Why does temperature decrease with increase in altitude?
The temperature decreases with increase in altitude, because the air is thinner, and not able to hold in as much heat the higher you go. The thinning of the ozone layer is not what is causing global warming, a combination of other factors, whether they are man made or not is still up in debate, are to blame. Without the ozone layer, Earth would recieve more ultraviolet radiation, but this would not increase the temperature of the planet. It would certainly kill off most life on land though. Fortunately, the ozone layer is quickly repairing itself, and we won’t have to worry about that.
The air around you is heated by the ground and solid objects on it as they are heated by the sun, not the other way around. Also, as pointed out by others, the air is thinner at higher elevations, so it cannot hold as much heat (or water vapor). So, the combination of being further from the ground and that the air is thinner results in cooler temperatures (the adiabatic lapse rate). As for the ozone, the destruction of it (in itself) shouldn’t cause any temperature change, because ozone (triatomic oxygen is generated by the effects of solar ultraviolet radiation on normal diatomic oxygen in the upper atmosphere. UV doesn’t have a whole lot of temperature effect on the earth, so if more hits the surface there shouldn’t be much change.
