Question

there is a correlation between the density of metal and their location in the interior of the earth

Answer 1

The density of metal and their location are corelated.

According to their depth and their quality different metal has different density.

Such as the density of Aluminium in kg/m^3 is 2830 and aluminium foil is 2700.

Now the relation is, if there is an increase in density of metal then their relative buoyancy of that metal increases.

Thank you hope you got and idea of their co relation.
