11. Global Tectonics Partial Melting
Partial melting is responsible for evolving mantle rock…
among other things this gives us continents.

12. Oceanic lithosphere –
general chemistry is
Fe, Mg rich in the form
of a rock “Basalt”
Continental lithosphere – general chemistry is
Si, O, Al, Na, K rich…in the form of a rock “Granite”

“Slab Pull”
Plate
Movement
“Plate Drag”
