Why does water freeze from top to bottom? Deep in the ocean it’s below freezing, why doesn’t it freeze?
There are several reasons. The salt in the ocean lowers the temperature needed to make it freeze. Currents stop the ice from bonding, and if Ice did freeze, it is less dense and floats.
The Short Answer
There are several reasons. The salt in the ocean lowers the temperature needed to make it freeze. Currents stop the ice from bonding, and if Ice did freeze, it is less dense and floats. But the main reason is the pressure, especially in deep water. To freeze, water needs to expand. Deep in the ocean, the pressure from the water stops it from being able to expand.
