According to a new study (http://www.sciencemag.org/content/344/6189/1265) by a group of U.S. geophysicists, a reservoir of water three times the volume of all of Earth’s oceans has been discovered inside a layer of blue rock 440 miles deep

Geophysicist Steve Jacobsen of **rthwestern University, who coauthored the study, says (http://www.theguardian.com/science/2014/jun/13/earth-may-have-underground-ocean-three-times-that-on-surface) it’s evidence the planet’s water bubbled up from somewhere underground.

The water is thought to be trapped in a layer of ringwoodite, a rock with a crystalline structure that acts like a sponge, to attract and trap the hydrogen and oxygen atoms that comprise water.
