Beautiful, bewildering, and bizarre - our oceans dominate our planet. How did they form? Why haven't they evaporated? Starting with the primordial weather burped out of the molten earth and rained back to earth as liquid; join us as we investigate the awesome power of our water world. Hold on tight as our time-machine propels you backwards and forwards through the geological history of a little rock we call home - Earth. We'll journey from the mind-bending beauty of coral reef shallows to the deepest depths of the Mariana Trench glimpsing everything in between. We'll take a tempestuous ride as the great oceans generate our wildest weather, and we'll even get to take a peak into our ocean's future. Join National Geographic for this hypnotic and colorful adventure- past, present and future - on a place called Earth... a truly Amazing Planet.
