Question

Why does ice stay at tge top of oceans instead of sinking to the bottom?

Answer 1

Answer: Ice is less dense than water.

-------

This is a property of water, one that is crucial for ocean life because the ice keeps the entire ocean from freezing in very cold temperatures. If the ocean froze over, much of the life would not be able to survive.

Ice is less dense than water because of the hydrogen bonds. In solid form, the hydrogen bonds orient themselves in such a way that the molecules are further apart, lowering the density of ice.

Answer 2

Because since the water is ocean water and it’s impure, the impure water freezes at the top while the “clean” water is at the bottom.
