Nature reveals some mysterious complexities about the water cycle of our planet, in particular, how much oceanic water is trapped inside the earth through plate tectonics. According to the study, about three times more than we thought.

The mantle of the earth consists of a puzzle of intertwined tectonic plates. When these plates collide and one slides under the other, water enters the subduction zone. Through a combination of heat and pressure, water is chemically transformed into "wet rocks," a hydrated mineral that locks up inside the plate and enters the earth's crust. Douglas Wiens, professor of Earth and Planetary Sciences at the University of Washington in St. Louis, wanted to find out how much water is absorbed in this way. It started at the Mariana Trench, the deepest natural formation on the planet seven miles below sea level.

After a whole year of listening to the rumors of the Mariana and Pacific plates 20 miles below the seabed, they discovered that the mantle contains four times the amount of water that was previously thought. To put this in perspective, that is as much water as all the oceans on Earth combined. The blue planet indeed.

If you think of the Earth as a vacuum, what goes in should come out more precisely, above. Scientists believe that most of the water consumed in the subduction zones is expelled as water vapor during volcanic eruptions.

Scientists believe that most of the water consumed in the subduction zones is expelled as water vapor during volcanic eruptions.

But here's the problem: these recent estimates from the University of Washington study reveal a huge imbalance in intake and outflow. Geologically speaking, the more water is transferred to the mantle, this means less water on the surface. And yet, Wiens points out that, for the last 550 million years, the oceans have been as they are now. New research in the trenches of Alaska and Central America will probably shed some light on this mystery.

Whether you are fascinated by the slow geological movement or not, it is a mystery worth discovering. Understand how water works in, around our planet and not only illuminate how we live here on Earth now, but how we could survive on some other planet. Someday.
