Temperature falls to -120 F at the mesopause. Thermosphere - extends above the mesosphere more than 100 miles. Zone of increasing temperature, but this is meaningless since there is in effect no atmosphere present. Heat Heat is a form of energy. Temperature is a measure of the quantity of heat energy.
Temperature is measured with a thermometer .
The most common, the alcohol thermometer, measures the differential expansion of red alcohol and the glass that encloses it. All weather is a function of heat transfer. There are three forms of heat transfer. Conduction - heat travels through material by molecular collisions. The analogy is a hot spoon.
