Narrated by Richard Kiley, the Emmy Award-winning documentary series Planet Earth explores the geological forces that have shaped and continue to influence life on our planet, whether they come from deep within the earth's crust or the farthest reaches of the solar system. This volume combines the episodes The Living Machine and The Blue Planet, examining both internal forces such as earthquakes and volcanos, as well as oceanic phenomena such as underwater hurricanes and tornadoes.DVD Features:Region [unknown]Keep CaseFull Frame - 1.33Interactive Features: Scene Access Interactive Menus
