WELL LETS SEE SALT SEAS HAVE SALT AND LAKES USUALLY DONT THERE FOR SALT WATER FREEZES SLOWER THAN FRESH HUMMMM I THINK THAT MAY BE YOU ANSWER.

There are at least three main reasons why lakes freeze more readily than the sea.
1. As elevation increases, temperature goes down. Lakes occur - obviously - more often above sea level than below sea level. So, on average their native temperature will be lower than the sea.
2. Lakes are closer to sources of fresh water run off. They have much less salt than the sea. Salt lowers freezing temperature in water. So, even when a lake and the sea is at 30 degrees fahrenheit, the sea is too salty to freeze.
3. Size. Lakes are by definition smaller than seas. They are a smaller reservoir of heat that the sea. As the air temperature goes down, the surface of the lake more quickly cools because it quickly dissipates the small heat reserve in the lake's water.
;-D Don't ask me to prove any of this!

While neither lakes nor oceans are pure H2O (they are both solutions with minerals disolved in them) the ocean has a far greater concentration. This higher concentration results in both a lower freezing temperature and a lower boiling point.

There is a lot more movement in a sea than in a lake.

thats cuz presence of salt in the sea water causes a lowering of the freezing point...moreover a solution will freeze when its vapour pressure equals the vapour pressure of pure solid solvent....
even so....that is the reason why salt is sprayed over in the driveways in front of houses after the snow...to delay the freezing of water.....

A solution of salt in water has a lower freezing point than that of pure water.

Lakes are way smaller and contain no salt. Come on, that was an easy one.

i guess that would be due to the difference in the size of both bodies of water and also the salt content

Come on, look at the size difference

salt water is harder to freeze
