Question

What is the key role that energy plays in the intraction among the four subsystems of the earth

Answer 1

Explanation:

Energy is not a physical unit. It is a philosophical concept and an accounting technique used to analyse mechanical and chemical exchanges. In quantum physics it is defined as a wavelength of light, in biology it is a synonym for metabolism, and in public utilities they say energy when they mean connectivity. Anybody who uses the word in any other context either does not know what he is talking about, or is peddling something you don't need.
