How did Earth's iron core form?

Answer 1

On the contrary, the Earth's Iron Core formed from impacts from meteorites and the heavier metal (Iron) which was delivered in those meteorites gradually sunk to the center of the Earth to form the core.

Answer 2

Earth's iron core formed through a process called planetary differentiation, where heavier elements like iron sank to the center of the Earth due to their higher density. During the early stages of Earth's formation, as the planet was still molten, dense materials like iron accumulated in the core, leading to the formation of a solid inner core and liquid outer core.
