How does the Earth work? Richard Hammond goes to go to the centre of the planet to find out. Using a giant 3D virtual Earth, Richard peels back the layers and shows where volcanoes come from, why earthquakes happen and even where to find diamonds.

Using stunning CGI, the latest satellite imagery and beautiful locations around the world, the story of how the Earth works has never been seen like this before. And in Richard Hammond's hands it is a story that has never told like this either!

What lies at the bottom of the oceans? What would happen if the planet lost its oceans? Richard Hammond is going to drain the oceans to find out.

Hidden beneath all that water are some of the biggest natural formations on earth: The longest mountain ranges, the tallest volcanoes and the deepest canyons.

Richard can reveal all this and more in a way never seen before, because he has the ultimate toy - a vast working 3D virtual Earth in a hangar.
