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: -These materials became the early mantle and crust. Droplets of iron, nickel, and other heavy metals gravitated to the center of Earth, becoming the early core. This important process is called planetary differentiation.

Detailed explanation-3: -Differentiation. The first stage of planetary development is called differentiation, the settling of dense material, like iron-rich minerals, into the center of a planet and the rising of less dense material, such as silicon-rich minerals, to the surface.

Detailed explanation-4: -The process by which heavy material sinks to the center of a planet while lighter material rises to the surface is called differentiation. The differentiation of Earth implies that our planet must have been at least partially molten in the past.

Detailed explanation-5: -Billions of years ago, the planetary blob that would become the Earth started out as a hot, viscous ball of rock. The heaviest material, mostly iron and nickel, sank to the center of the new planet and became its core.
