The Sculptor
"Earth is never finished. Forces continually carve, carry, and rebuild."
The Process Engine
Here the ontology shifts from "what Earth is made of" to "how Earth's surface is continuously reorganized." We connect internal tectonic energy with external atmospheric energy to understand the absolute evolution of landscapes over deep time.
