Plate tectonics

The Earth's crust is not one solid piece of rock. It is broken up into several larger and smaller tectonic plates. The tectonic plates move in specific directions as a result of convection currents in the mantle. Geographer Dan Raven-Ellison demonstrates the movement of the earth’s crust explaining how tectonic plates interact at plate boundaries. Through the use of animated hand-drawn diagrams, Dan is able to show the movement at different plate boundaries.
