      The ocean does freeze, just take a look at the North and South poles. This is because sea water freezes at a lower temperature than freshwater. The ambient temperature of the sea is also generally above this.

      Check out this cool video of a scientist freezing fresh and ocean water – https://www.youtube.com/watch?v=h1NLKi0X41Q

      Did you also know that boiling water also freezes quicker than water at room temperature!
