Water leaking into the Earth may be wrapping the core in crystals, a study has suggested.
"For years, it has been believed that material exchange between Earth's core and mantle is small.
We still don't know everything about our planet's insidesThe Earth's core is only about 1,800 miles under our feet, but it's more inaccessible than Mars.
Dan Shim/ASUTo support their hypothesis, the scientists simulated the high-pressure conditions of the outer core in the lab.
He added that his calculations show that he can explain the E-prime layer "reasonably well" with a range of water transportation scenarios.
