ELI5: Why the bottom of the ocean isn't frozen ?

Don't it gets colder as you keep going down ? So why isn't the bottom like solid ice or something ?

its because of pressure. while the bottom of the ocean is close to freezing, there is a unimaginable amount of pressure down there. and as everyone knows, when water freezes it expands. as the pressure increases in the water, the freezing point becomes lower and lower because the forces expanding the water to become ice aren't as strong as the pressure acting on the molecules.
