How much weight per Unit area falls on the surface of the Earh's Core?

Question

correction=Earth's solid core

Answer 1

Actually, surprisingly very little is factually known about the Earth's deeper underlayers, especially the core. Although there is general concensus that certain chemical compounds and molton rock exist down there we have never been able to dig deep enough to see any of it for ourselves.

But to answer your question, if the core is not solid and is actually hollow or filled with some fluid like molton rock, then there would be virtually no weight on the "core" becuase the surface of the earth would sustain itself by spreading weight over it's own area, sort of like an arch except spherical. Also, consider that the gravity of earth is due to it's total mass. The core of the earth will only constitute a portion of the earth's mass and contribute to the pull of gravity that we feel. But there is no reason to believe that there is some special tiny dot at the very center that pulls everything else toward it.

Answer 2

Zero

Answer 3

How big is the "Earh's" core? Is it the size of a ping-pong ball, or is it bigger than tha?
