Question and Answer

Why oceans do not freeze? Give two reasons.

Answer

The ocean water has salt dissolved in it, unlike the water found in lakes, ponds, and rivers. The salt in the water does not make the water cold, therefore, it prevents the water to form ice. The highest concentration of salt in ocean water lowers the freezing point from \(32\degree F\) to \(28\degree F\). Due to the Earth's internal heating, the temperature of the water deep in the ocean is significantly warmer and does not allow the water to freeze.
