The Origins of Weather

This short documentary illustrates the factors that produce the various climates on the Earth. A combination of live action footage and animation demonstrates the Earth's dynamic heat exchange—the effect of the sun's heat and the movement of air masses. The equilibrium of the Earth’s atmosphere and the fact that 75% of the planet’s surface is covered by water are factors in preventing the Earth from exhibiting the kinds of extreme climates that many other celestial bodies do.
