Why are the Earth’s oceans so cold when the Earth at the same depths is so hot?

Water changes density very slightly with temperature, and since it is fluid the denser, colder water settles on the bottom. Any water that gets warmed by the Earth’s internal heat would rise up and be replaced by more cold water, which in turn keeps the ocean floor itself cold.

It’s all about the layers, my dude. Earth’s crust insulates the inner heat, and the oceans are constantly mixing with cold water from the poles. Plus, sunlight only heats the surface, so deeper water stays chilly. 🌊💨🔥
