Earth: The Power of the Planet
Miniseries
In each episode, geologist Dr. Iain Stewart explains the effects and importance of a specific force of nature, such as wind or volcanism. He also examines the various ways in which it shapes planet earth itself and influences life on it, often in conjunction with other natural forces, and sometimes with lifeforms, as in the 'apocalyptically' grave case of global warming.

- Volcano
E1VolcanoVolcanoes have a fearsome reputation. In reality, they are the most important force in the creation of the planet as we know it today. Iain abseils into a lava lake and cave dives in a cenote to show how the heat that fuels volcanoes also drives some of the most fundamental processes on the planet. - Ice
E3IceIce may be nothing more than frozen water but, as Iain explains, it holds extraordinary power. Descending 150m down a frozen waterfall, he sees a glacier in action from below and discovers why the huge Jacobshaven glacier is retreating, he shows how it shaped our past and may now threaten our future. - Rare Earth
E5Rare EarthOur planet is unique within the solar system. Four-and-a-half billion years ago it had a 'twin' named Theia which was absorbed into the Earth, increasing its gravity and allowing it to form an atmosphere. Iain travels to Meteor Crater in Arizona to explore the atmosphere's role in protecting us from bombardment by meteorites, and finds that life on earth only prospers because it is provided with right amount of heat from the sun.
