The heat equation is a parabolic partial differential equation that describes the distribution of heat (or variation in temperature) in a given region over time.
Redistribution of Heat. Key idea: Planets are not evenly heated by the Sun. The uneven heat is redistributed my moving air masses, water vapor and ocean currents (on Earth anyway). The non-uniform heating and the redistribution of heat produce global circulation of the atmosphere, global climate and local weather patterns.
