'Writing in the journal Nature, scientists on Wednesday said they had found an elusive mineral pointing to the existence of a vast reservoir deep in Earth's mantle, 400-600 kilometres (250-375 miles) beneath our feet.

It may hold as much water as all the planet's oceans combined, they believe.

The evidence comes from a water-loving mineral called ringwoodite that came from the so-called transition zone sandwiched between the upper and lower layers of Earth's mantle, they said.

Analysis shows that a whopping 1.5 percent of the rock comprises molecules of water.

The find backs once-contested theories that the transition zone, or at least significant parts of it, is water-rich, the investigators said.

"This sample really provides extremely strong confirmation that there are local wet spots deep in the Earth in this area," said Graham Pearson of Canada's University of Alberta, who led the research.

"That particular zone in the Earth, the transition zone, might have as much water as all the world's oceans put together."'

We have plenty of water in the surface, it just needs to be desalinated.
 
Will we find Nessie at last?

Well, now we can be reading this is proof that the Biblical flood was possible.
 
Water is a fascinating substance. Liquid. Solid. Gas. Break it down to its two components, oxygen and hydrogen, has you have a very powerful flammable mixture. But combined it is the most common way to extinguish a fire.

Opaque yet reflective, bends light, adhesive.

Almost all kids are fascinated by water, and to be honest I get it.

Yet the one unique property of water, which is shared by very few other substances, is the property that makes the solid form less dense than the liquid form.

It's also got an almost impossibly high boiling point, given how tiny the molecule is.

It's surface tension is off the charts compared to almost any other liquid at room temperature (mercury is an exception, natch).

When you study it's physical chemistry, it's really dramatic on how these properties fundamentally impact life on this planet. (ex- if ice sank, the world would be a frozen ball).

And non-compressible; and also known as the "universal solvent."
