Earth: The Biography - Volcanoes

Seizoen: 1 - Aflevering: 1 / 1 - Eerst uitgezonden: 20 november 2007 - Episode ID: 83475

Volcanoes are one of nature's most awesome and destructive forces, but they are also the life force and architect of our planet. They can raise up great mountains and create new land, or they can level cities and destroy entire civilizations. They provide a glimpse of the power of Earth's internal heat source, without which it would have become a dead planet millions of years ago. In this episode, Iain takes us on a journey to some of the most dramatic places on Earth, starting in Ethiopia.
