TV Program: Earth Revealed: Introductory Geology: Plate Dynamics

This episode dealt with plate dynamics. The earth's crust is made of twelve large plates which are constantly shifting. When enough pressure builds up that the plates slide against one another, earthquakes result. This program explained the process of subduction, as well as the convection motion in the mantle layer.
