• inner core

layer of Earth directly under the crust; made of magma

NGSS.MS-ESS2-3

the process that creates new sea floor as plates move away from each other at the mid-ocean ridges; the mechanism for plate tectonics

• continental drift

• land bridges

• uplift

• seafloor spreading

The theory that the Earth's lithosphere is broken into pieces that are in constant motion, driven by convection currents in the mantle.

• land bridges

• plate tectonics

• continental drift

• seafloor spreading
