Why does the ocean elevate?

"Sure I suppose water gets denser as more of it is piled upon itself and it expands and contracts like all matter under pressure."

Not entirely true. Pressure may cause a change of state. Under pressure ice can revert to water, since water occupies a lesser volume.
 
ice less dense than water!!!!!!!!!????????
you see my humble fellow forum member, you come to such a conclusion
because YOU weigh an ice cube to the world ocean!!!!!!!!!!!!!!
iiiiiiiiiiffffffff ice lesssssssssssss dense than water
tttttthheeeeeeeeennnnnnn water lesssssssss dense than gas!!!!

I SAY ICE DENSER THAN WATER ALSO WATER DENSER THAN GAS
I SSSSSSSSSAAAYYYYYYYY
DENSER WEIGHS MORRRRRRREEEE THEN DENSE
GRAB AND ICE BLOCK AND WEIGHT IT AGAINST WATER OF THE SAME VOLUME
AS THE ICEBLOCK!!!!!!!!!!!!
WHICH ONE WEIGHTS MORE????????????
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiicccccccccccccccccccccccceeeeeeeeeeeeee

HAVE A NICE DAY!
 
Philocrazy, whats up with your post? First of all, Ice is less dense than water. Period. I learned that in 7th grade. Secondly, your raving with caps and excessive letters is uneeded.

Later

ofcourse you know
but what is ice huh?
water hmmmmm
water is less dense than water everyone!!!!!!!
hahahahahahahaha
hahahaha
woodchips is more dense than wood
oil is more dense than water
your brain more dense than an ape's thickskull,thats why you're so intellegent
 
P.S. Yes Ice is water, but it crystalizes below 32 degrees farenheit to form a unique structure... a structure that increases volume with the same amount of mass... hence, it expans. This is why a water bottle, filled to the brim (or a pop can) will "explode" in the freezer.
 
Well in reference to the Panama Canal, I think the reason is due to the proximity of the Divergent Plate Boundary to that region. That thermal source, and consequent "bulge" it produces in the surface of the Earth, causes a bulge in the ocean, though I'm not sure to what extent (so I'm not sure it is the answer).

But that answer makes most sense.

Atmospheric pressure also causes changes in Ocean altitude, lower pressure areas have a bulge, higher pressure areas have a depression or bowl.

Click to expand...

Pressure will only cause Ice to stay Ice...or Water to become Ice, please refer to a Phase Diagram.

Water can not become "more dense" if pressure is applied, it is non-compressable.

Look at about 260 deg near point III.
 
I suspect you might be well up on the super-dense water found in the inter-layer space of hydrophilic clays, Catastrophe.
 
No it wouldn't, I stand corrected, but you could have waited till I had a chance to arrive, this is the first I've viewed the forum. You are too impatient ;)

Anyway, thanks for the compression data.
