Quizplus · Accepted Answer

When the terrestrial worlds were forming, they were molten throughout. In this molten state, denser materials such as iron and nickel sank towards the center of the planet due to their own gravity. This process is known as differentiation, and it resulted in the terrestrial planets having a dense metallic core. Therefore, the cores of terrestrial worlds are made mostly of metal because metals sunk to the centers a long time ago when the interiors were molten throughout.
