Rare diamonds suggest water lurks much deeper in Earth’s interior than scientists thought

A rare type of diamond may suggest that water can penetrate deeper into Earth’s interior than scientists previously thought. 

Though more than 70% of our planet is covered with water, there is also water in minerals more than 200 miles (322 kilometers) underground, including in the upper mantle, the semi malleable layer that the crust “floats” on top of. Scientists have long thought that as the upper mantle transitions into the hotter, denser lower mantle, minerals can hold far less water.
