their relative densities
Explanation:
The relative densities of the earth's materials can be inferred by the arrangement of the earth layers.
Compositionally, the earth is made up of three distinct layers; core, mantle and the crust.
- The crust is the thin outermost layer of the earth.
- The mantle straddles the zone between the core and crust.
- The core is the innermost layer of the earth.
During the formation of the earth, materials differentiated into different layers based on density.
The densest materials settled in the core and they are made up of iron and nickel metals.
The lightest materials of silicate affinity partitioned to the crust.
The mantle contained materials whose density straddles between the crust and core.
