Question

why temperature changes with increasing height?

Answer 1

Answer:

Temperatures decrease with altitude in the troposphere at a rate of about 6.5 degrees Celsius (11.7 degrees Fahrenheit) per kilometer, depending on the weather. This occurs as a result of decreasing air pressure with altitude. As pressure decreases, air expands, and it cools as it does so.

Answer 2

$\huge \colorbox{violet}{Answer}$

In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.
