Question: How hot is the core of the world

Duncan McNicholl answered on 4 Nov 2017:

Really really really. I don’t actually know the temperature in degrees, but I do know that it’s so hot that rocks melt. When a volcano erupts and lava goes everywhere, that lava is melted rocks from just under the surface of the earth, like maybe ten or twenty miles down, and the earth just keeps getting hotter the further down you go, and the core is something like six thousand miles deep, so really really really hot, yeah. Really.
