On the Move, Tectonic Plates Continue to Shape Our World

In On the Move, Tectonic Plates Continue to Shape Our World, narrator Richard Hammond describes how shifting tectonic plates are responsible for earthquakes and mountain ranges, and even the creation of new land. When plates collide, the land buckles and creates mountain ranges like the Alps and the Himalayas. Mount Everest, the highest peak on the planet, gets higher by two-tenths of an inch each year because the tectonic plates are still pushing together. This video is excerpted from BBC's Earth Machine, in which Richard Hammond goes to the center of the planet to find out how the Earth works.
