Answer:
Crust density- 2.6 grams per cubic meter
mantle density- 4.5g/cm^{3}
core density- 12.2 g/cm^{3}
Explanation: Crust-The crust, with an average density of around 2.6 grams per cubic centimeter (g/cm3), is less dense than the mantle (average density of approximately 3.4 g/cm3 near the surface, but more than that at depth), and so it is floating on the “plastic” mantle.
Mantle-The mantle consists of iron and magnesium silicates and magnesium oxides, so it is more similar to the rocks of Earth's surface than to the materials in the core. The mantle has a density of 4.5 g/cm3, and temperatures in the range of 1000-1500 oC.
Core-The density of the inner 'solid' core is between 9.9-12.2 g/cm3 and the outer core's density is between 12.6-13 g/cm3.
