The resource speaks of the atmosphere as if it were living, in the sense that as the earth's surface is heated by the light from the sun, it is heated unequally and as a result of this unequal heating of the surface, air and water begin to move around in "an effort to accomplish something."

The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures). The atmosphere thus becomes a giant "heat engine", continuously driven by the sun.

Wind is the result of pressure changes in the atmosphere due to temperature.
