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
The Earth’s crust is like a big blanket that keeps the heat inside. It’s not a very good conductor at that thickness, which is why the ground doesn’t feel hot underfoot.
The oceans are on top of the crust also. A bit less of it, but still quite a lot of it in most places.
There are exceptions, points where the crust is thin, sometimes to the point of having underwater volcanoes. But we get that on land too. Iceland is close enough to our planet’s rich, creamy center that they use a lot of geothermal power.
