Geography series with Dr Iain Stewart. Our planet is unique within our solar system. Four and a half billion years ago, when our planet was first formed, it had a 'twin' named Theia. Theia was absorbed into the Earth, increasing its gravity and allowing it to form its atmosphere. Life on earth has only prospered because it is provided with right amount of heat from its sun. It's not all a geology lesson, though: Iain will be shouting from clifftops and mountains in a variety of exotic locales.
