What is the best estimate of the densities of the various layers of the Earth?
Estimates vary, but some approximate values should be as follows (in grams per cubic centimeter):Continental Crust: 2.7 to 3.0 Oceanic Crust: 3.0 to 3.3 Mantle (silicates): 3.3 to 5.7 (increasing with depth?) Outer Core (liquid): 9.9 to 12.2 Inner Core (solid): 12.6 to 13.0
Thanks for the question.
