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. Convection - heat transfer by actual motion. Radiation - transfer of energy by electromagnetic waves.
