This series travels the globe to reveal the geological processes that shaped our planet. Each episode examines how the features we see today have been formed over millions of years—whether by colliding continents, volcanic eruption or the abrasive power of vast ice sheets or other means. Geologists in the main and others guide the viewer to an understanding of the formation of today's Earth.
