While the world is worried about our DRY PLANET, Scientists on Friday said massive amounts of water appear to exist deep beneath the planet's surface, trapped in a rocky layer of the mantle at depths between 250 miles and 410 miles (410 km to 660 km). Don't plan of drilling your well to that depth and pumping it out. The water is not liquid - or any other familiar form like ice or vapor. It is locked inside the molecular structure of minerals called ringwoodite and wadsleyite in mantle rock that possesses the remarkable ability to absorb water like a sponge. Unfortnately, it is not an accessible resource in any way, but the discovery alters our thoughts about the composition of the Earth. Complete story on Reuters.
