plates (slabs of rock). Plate Tectonic Theory: plates

(continents) move a few centimeters each year.

Which continents are

on multiple plates?

Plate Movement Convection: spread of heat through

movement of fluid substance Gravity: oceanic plates (heavy) are

pulled under land plates (light)

Divergent Movin’ apart Most common in the ocean

Palms face down with index

fingers touching. Now, pull your hands
