Why does an iceberg sit mostly under the ocean water surrounding it,

Because their density is close young padawan (or old fart?).

The density of water is 1.0 gm/cm^3

Use proper units, g/cm^3 not gm/cm^3.


Ice is 0.91 gm/cm^3. That is actually a pretty big difference relative to
other materials. Yet ice doesn't ride on top of ice. It sits in it (most
of it below the surface, in fact), and it does so because the mass of ice is
sufficient to displace an equal amount of water.

Pfffff... 0.91 and 1 *are* close values. and that difference explains
perfectly why most of an iceberg is in water.

That is yet another evidence that you don't understand how buyoancy
work. Really pathetic.

Let's play a bit to see if you will finally figure it out.

There is a solid ball which density is 0.5. You put it in water. What
ratio of the ball is emerged?

We hold our breath.....


In terms of PT phase changes will complete the requirements .

Tell that to Ron hwo insist that he slab does not have to be denser.

If you will check my posts you will note that I have stated on a number
of
times, [...]

Snip backpedaling.
Idiot, you evoke sinking icecube to defent your lost case that less
dense slab can sink in the mantle.

And it is a valid analogy.

It is not at all, because icecubes *float*, they don't sink to the
bottom of water.
