Heh... Pellucidar... not E. R. Burroughs’ best work, but entertaining enough. :’)
Where can I read about these wierd things?
http://bible.cc/genesis/1-7.htm. The firmament has a few definitions, including the heavens, the air in which birds fly, and is also known as the expanse.

It would be more like the atmosphere of Jupiter, which it isnt. Water in the mantle would mean a gaseous core. Which is not the case.

As water enters the mantle(and it does through subduction zones) it becomes supercritical, meaning in a geseous/liquid state. It would penetrate back up through the mantle rock realizing its liquid state through underwater volcanism and other means. Since the core of the earth is iron and a supercritical liquid is lighter, it will always naturally reenter the most stable state.
Now there’s some science for you.
There’s something to be said for it.
Water does seem to lubricate the action of subduction zones. And consider the planet Venus, which has neither water nor active subduction zones.
Subducted oceanic mud gives up its water gradually, and reluctantly, usually having quite a bit left to vaporize explosively when it finds a volcanic outlet.
It does, especially at slip/strike faults. And some water obviously enters with the subduction. I have taken several geology courses in my studies, and while Im not anything of an expert like other claim to be, there are explanations. That is what is great about science. What doesnt work as a theory is discarded or changed and refined.
Its not a suprise that most of the underwater volcanic activity its located at these zones. Its called the ring of fire for a reason. Supercritical water and superheated water are very explosive at the high pressures.
Amazingly, the earths water is really a miniscule amount | 5/15/2012 | thanks central_va.The Louis Frank keyword:
