SOLAR SYSTEM

Detailed explanation-1: -Denser materials, like iron and nickel, sank to the core . Lighter materials, like aluminum and silicon, stayed closer to the Earth’s surface. The process in which the chemical elements separated by density is called planetary differentiation.

Detailed explanation-2: -Planetary differentiation is the separation of different constituents of planetary materials resulting in the formation of distinct compositional layers. Denser material tends to sink into the center and less dense material rises toward the surface.

Detailed explanation-3: -When planets begin to melt, the materials in them begin to separate from one another. The heaviest materials, such as metallic iron, sink to form cores. Low-density magmas rise, forming crusts. This process is called differentiation.

Detailed explanation-4: -Earth, by contrast, is a highly differentiated body with a metallic core surrounded by a rocky silicate mantle and its crust.

Detailed explanation-5: -In planetary science, planetary differentiation is the process by which the chemical elements of a planetary body accumulate in different areas of that body, due to their physical or chemical behavior (e.g. density and chemical affinities).

Detailed explanation-6: -However, density determines which particles will be closer and which will be furthest from the center. This results in the layering of Earth and other planets, with the densest layers closest to the center.
