On: All of Earth's water in a single sphere (2019)

[FredPret]

"Groundwater" is a little ambiguous - H2O in the mantle is also "ground water", no?

[pfdietz → FredPret]

No, that "water" is actually hydroxyl groups in minerals.

[chrisco255 → pfdietz]

No it comes out of the tap as water.

[mkl → chrisco255]

No tap water comes from the mantle.

[pfdietz → chrisco255]

That's water going into the mantle.

No, it’s completely inaccessible. Unless you are just playing word games, then sure.

[ClumsyPilot → DiggyJohnson]

Geologically it probably isn’t. If all surface oceans disappeared, some of that water would likely come out to the surface and form new bodies of water, over millions of years.

[moralestapia → FredPret]

It's not. The mantle is hundreds of kilometers further down.
