Why do mountains triangular in shape? How much rain must fall to start a river? How does one grain of sand become an entire dune? Join National Geographic as we explore how our Amazing Planet is sculpted. But hold on tight, this is no ordinary view.
National Geographic investigates the awesome power of our water world by journeying into the mind-bending beauty of coral reef shallows to the deepest depths of the Mariana Trench while glimpsing everything in between.
National Geographic cameras travel to Iceland, Africa, Japan, California, and Greece to record how the huge plates of the earth's crust crash together and spread apart causing ground-shattering earthquakes and volcanic eruptions.
