Each relationship between each layer is different. Like the mantle and the outer core. Its like the mantle is solid and it starts to soften and turn to liquid the deeper you go. Or like the outer core and the inner core . The outer core starts to get harder and denser and the deeper you go the solider it gets. Like the mantle and the crust too. The mantle gets a little more solid and becomes the crust.
As the depth increases, the density increases also.
The density of the outer core is between the 10g/cm³ and 12,3g/cm³.
between 12.6 and 13 g/cm3
the relationship is technologies trikes
uuu
They differ from the earths axis in relationship to its position during its one year revolution.
How is Mercury's density is about high as the earths density
because of electrons
the heat makes the density less or more dence depending were it is in the earths layers
A map scale.
the tilt of earths axis relative to the sun.
== == The average density of the planet Earth is 5.52 (Standardized Result 5.52 g/cm3) the density of core of earth is 8 g/cm3
