Question

The density of the Earth in the core immediately after the mantle is _______

(a) 8 g/cc

(b) 7.6 g/cc

(c) 9.9 g/cc

(d) 8.7 g/cc

The question was posed to me in class test.

I'd like to ask this question from The Mantle, The Core in division Internal Structure of the Earth of Engineering Geology

Answer 1

The correct option is (c) 9.9 g/cc

The best I can explain: At the base of the mantle, density is inferred as 5.7 g/cc that jumps to 9.9 g/cc at the top of the core.
