We all know what water is, right?
 
It's runny wet stuff that we all need in order to survive, right?
 
If it's frozen, it's called ice, or maybe snow, a solid.
 
If it's boiled, it becomes a gas, steam.
 
But now scientists are telling us that they've discovered non liquid water.
 
Not only is it non liquid, it's not frozen or boiled. In fact it's nothing we've ever heard of before.
 
See the link for more info.

WASHINGTON - If you want to find Earth's vast reservoirs of water, you may have to look beyond the obvious places like the oceans and polar ice caps.
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).
But do not expect to quench your thirst down there. The water is not liquid - or any other familiar form like ice or vapour. 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.
Can this really be categorised as water?

Matter can exist in six states that I know of - Solid, liquid, gas, plasma, filament, and sublimate. If there's a seventh... Oh no, my brain hurts....

But in the context of the original article it seems to me all this underground ocean is is a vast region of saturated rock. That's not all that weird really...

Well yes, in a way, but not in the way we would usually expect.
 
Reading the full article, my interpretation is that the rock has the H2O molecules embedded within the rock molecules.
 
Had it simply been vast reserves of water very deep underground, that would have been easy to understand and accept.
 
As an afterthought, if it isn't a liquid, surely it can't be water?

Caldrail: Did you read the source material?
 
What are your thoughts on it?
It's not that I was born in Ireland,
It's the Ireland that was born in me.

Amorphous solid is another I can think of. Glass is an amorphous solid, it appears solid but flows like water over thousands of years or when heated up.

The Ringwoodite is a hydrated mineral. The water does not exist as H2O water but rather as hydroxide ions (OH) inside the mineral structure of the Ringwoodite. Kind of like the way sugar dissolves in water the water has dissolved into the rock. Under the right temperature and pressure the water could be extracted.

A more common form* of hydrated mineral is lime. Lime is CaO (calcium oxide) but absorbs water to become Ca(OH)2

Ca(OH)2 → CaO + H2O

The process for Ringwoodite is similar and this is how the "water" is stored inside the earth.

*Well actually less common I think but more in the public consciousness.

Thanks for the explanation.
