Formation of Earth's Layered Structure

Melting of iron and nickel

Extraction of heavy metals

Uniform composition and density

Chemical differentiation (correct)

Melting point of iron and nickel was reached, causing them to settle to Earth’s center

Denser iron and nickel settled to the center while lighter silicates formed the mantle and crust (correct)

Heavy metals were extracted from the Earth's interior and concentrated in the developing crust

The ascending molten masses led to the formation of different layers

Ascending molten masses (correct)

Chemical differentiation

Uniform composition and density

Formation of three subterranean sections
