 
                                            Earth: The Power of the Planet
    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.
