Scientists from the Washington University in St. Louis have revealed in a recent study that the earth’s Crust is swallowing a staggering amount of water as a result of tectonic activity.
But the scientists aren’t quite sure where it is going!
Scientists do not know where it ends up after being pulled down though they think that most of it returns to the atmosphere as water vapor through faraway volcanic eruptions. But scientists are sure that more water is being pulled into earth’s Crust than it came out.
The earth’s mantle consists of an interlocking puzzle of tectonic plates. When there is a movement of these tectonic plates, water gets pulled deeper into the earth’s crust
Using seismographs placed across the Mariana Trench, scientists found that the mantle contains four times the amount of water than previously thought …that’s almost all the water that oceans have. Seismic images revealed that the hydrated rock at the Mariana Trench extends nearly 20 miles beneath the seafloor, locking water within.
At seven miles below sea level, the Mariana Trench is the deepest part of the world’s oceans.
