Dissolved salts in water contribute to a decrease of the freezing point.
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
For ultrapure water a temperature of 0 oC is needed.
Ocean water has a lower freezing point than fresh water due to the presence of salt, which lowers the freezing point of water. The salt in ocean water lowers the freezing point by making it more difficult for water molecules to form solid ice crystals. This is why ocean water typically needs to reach a lower temperature to freeze compared to fresh water.
The amount of energy required to freeze water depends on the initial temperature of the water and the desired final temperature (0°C for freezing water). To calculate the power in watts needed to freeze water, you would need to know the mass of water, its initial temperature, and the time over which you want to freeze it.
The materials needed for the experiment are: two containers to hold the water, hot water, cold water, thermometers to measure the temperature, a freezer to freeze the water, and a timer to record the time it takes for each to freeze.
cos it contains salt :)
because the ocean has salt in it rather than freshwater lake Because fresh water on the surface of a lake is frozen. Under similar conditions, salt water is not frozen.

The ocean water has a high amount of dissolved salts.
Three things needed in a fresh water habitat are precipitation, temperature, and oxygen.

the chemistry of cohesion
About 70% of the Earth surface is covered with water, and most of that is the ocean. Only a small portion of the Earth's water is freshwater, which is found in lakes, rivers and groundwater. Freshwater is needed for drinking, farming, and washing.
