Question

There is correlation between the density of metals and their location in the interior of the earth

Answer 1

The Earths interior consist of mantle, curst and core. The density within the Earths interior is distributed and even depends on the seismic velocities. The upper mantle of the earths crust is generally termed as transitional layer and in this layer the density if considered to be very much proportional and aligned to compressed waves velocity. A little bit of density variation is further found in the core and lower mantle layer.

This is also the region that is considered to be rich in FeO rocks. The ratio of the rocks to the density might vary ranging from + or – 10 percent to + or – 12 percent by weight. In this layer, you may find rich concentration of Packed Oxides and silica.

The outer most layer of the earth is much lower as compared to iron density by less than 10 percent.

Answer 2

Gravity is the denser and heaviest compound of the earth that attracts elements at the center of the earth.

Due to this high pressure, the iron becomes denser due to uranium and thorium which are light in their molten form.

These elements participate in the heating process that makes the magma to drive tectonic plates.
