I saw this question somewhere else, but if the Earth’s core is so hot, then why are the deepest parts of the Oceans so cold? Shouldn’t they be boiling or at least warmer?
In: Planetary Science
There’s still a lot of crust between the ocean floor and the mantle of the Earth.
There are volcanic vents underneath the ocean floor, but that newly heated water rises up rather than staying on the ocean floor.
The cold ocean floor is at about 4°C because that is the temperature at which water is densest, so slightly colder water will rise, and slightly warmer water will rise.
