WebDec 18, 2015 · $\begingroup$ I think Earth's outer core layer is still molten but the inner core is solid (due to pressure, etc). Also the solid part is growing as the molten part around it crystallises. So the question may benefit from editing to make it more clear. (Still a good question in my opinion.) $\endgroup$ WebJul 30, 2024 · The Earth's core has a similar temperature to the surface of the Sun After a quake, seismic waves travel through the Earth, changing their form and direction depending on the materials they pass through.
