The Earth's Biggest Water Cycle

Subduction zones swallow the seafloor at deep sea trenches, starting a water cycle that involves the interior of the Earth. Take a tour through the subduction factory, from black smokers on the seafloor, to the world’s largest earthquakes and most explosive volcanic eruptions, following the water that links all of these processes. The ultimate fate of the oceans hangs in the balance of this deep earth water cycle.
