Climate scientists say they have solved riddle of rising sea

Can ocean tectonic plate/volcano/crust activity cause the sea level to rise from displacement?

and maybe another small contributing factor is meteor matter falling into the oceans.

How many tons of meteors hit earth each year? Does that mean the Earth has gained mass over millions of Years?

Yes I would say it could. If sea levels rise as they have, that means there is more mass in the seas, hence the sea-floor will be depressed. So islands in the oceans will seem to be suffering sea level rises greater than continents. They are being pulled under.

IF 70% of the mass gained by meteors is destined to land in the oceans, because 70% of the Earth's surface is covered by oceans THEN
the earth will inevitably flood because the sea floor will rise but, so will the land rise, but because its 70% where the water resides the water will have nowhere else to go but to cover the land... and maybe Earth will become a planet like Neptune or Uranus in millions or billions of years...

END IF

Flawed logic in my then section, I suspect. Wait to see if a math dude can figure it out and post something.

You have been following the Life on Mercury thread? In there we have discussed the progressive loss of water from the planet Earth. Without meteors and soil erosion filling in the oceans the water level would be a kilometer lower than it is today! (a wild guess but it won't be that far out).

I suppose the reasoning is sound, although there are huge water reserves in the earth's mantle and crust in the form of chemical bonds in the minerals. As minerals break down, in some cases, through chemical erosion, additional water, oxygen, and hydrogen based compounds are released.

I'll see if I can find some specific minerals as references, but some crystals actually incorporate water molecules which bind the other elements and compounds.

Also, if you dissolve dolomite in an acid over a long time, you will create "new" water in small quantities.

Ok, Topaz is a good example:

Al2SiO4(F,OH)2

Two moles of acid plus one mole of topaz should give two moles of water, eventually. Notice, I didn't say in human time scales, because in nature this could happen instantaneously, or it could require absurd time scales, depending on temperature, pressure, and saturation.

Gypsum is a perfect example:

CaSO4·2H2O

Two moles of water per mole of crystal!

Amazing...

http://en.wikipedia.org/wiki/Garnet

Under the right conditions in the presence of Hydrogen, Garnets could produce huge amounts of water by releasing Oxygen.

Although it's possible the reverse happened more often than not...

Perhaps water vapor in the upper atmosphere was destroyed by solar or cosmic radiation, with the hydrogen escaping, and then the free oxygen bonded to the rocks....

Anyway, water, or it's components, could be incorporated in rocks and minerals either as "inclusions" or "impurities" or as the basic building blocks of those minerals.

Both modern science and the Bible agree on at least one thing: The Earth was totally covered in water at least one time early in it's history, before continents existed.

The "excess" water must have gone somewhere, and that implies being included chemically in the rocks that make up the mantle and crust.
