Pure water has a density of 1g/cm3. ... The average temp of . surface. sea water is 17.5 ºC (63.5 ºF). 75% of ... When ocean water freezes into icebergs and ice sheets, the ice is made of pure water with no salt. That salt is left in the water, so the ocean becomes saltier and denser. (This can be related to the marble demonstration - if all ...

When ocean water freezes into icebergs and ice sheets, the ice is made of pure water with no salt. That salt is left in the water, so the ocean becomes saltier and denser. (This can be related to the marble demonstration - if all of the salt remained but a few marbles were removed, (became ice) then there would be more salt per marble).
