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: -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-3: -In planetary science, planetary differentiation is a process by which the denser portions of a planet will sink to the center; while less dense materials rise to the surface. Such a process tends to create a core, crust, and mantle.

Detailed explanation-4: -The differentiation, or organization, of the Earth into layers is perhaps the most significant event in its history. It led to the formation of a core, a crust, and eventually continents. The light elements were driven from the interior to form an ocean and atmosphere. These four blocks are the same size.
