The Moving Earth
"How does motion create the rhythms of life?"
The Causal Engine
Geography does not treat planetary motion as mere astronomy. The Earth's tilt, spin, and orbit form the master engine driving all surface processes. Motion dictates illumination. Illumination dictates heat. Heat dictates pressure. Pressure dictates wind. Wind dictates climate.

We now understand the address and the motion. The Earth is spinning and orbiting, creating the thermal differences that drive the wind and the rain. But what is this spinning sphere actually made of? We must cut through the crust and look at the heat burning inside.
