HISTORY goes to the ends of the earth to find where our world began. Forged from fire and ice, formed by floods, volcanoes, asteroids and earthquakes, our planet tells a dynamic geological story. What are mega-tsunamis? What happens when you have millions of years of rain? Visual effects, location filming and stunning aerial photography bring viewers back 4.5 billion years to enjoy a unique window on our world. How the Earth Was Made peels back time like layers of rock to reveal the origins of the place we call home.
