Interestingly put, this question. It makes one feel that water in other parts of the world does not sink to the bottom, so there must be a gap above the sea floor! Maybe you mean why does the ice float to the top? Because it's lighter, that's why.
Surface water slainity is higher in tropical regions.
Cut off at the top. cannot see north or south poles.
Water evaporates more from areas near the equator.
They are the same because each are extremely cold,and dry climates.It is different because the North Pole is surrounded by water, and the South Pole is land.

Anything to do with the north and south poles. Water molecules (and some others) have polar regions.
All fresh water is stored in the ice shelves of the north and south poles.
According to what we know Mars has no grass on its surface but there are ice caps at the north and south poles.
the north and south poles for most of the time.
Surface water slainity is higher in tropical regions.
Thermohaline circulation is the process of cold water at the poles creeping along the ocean floor. It meets with north and south polar water creates a dawdling subsurface circulation.
