Where are the heavier components of earth located?

The heavier components of Earth, such as iron and nickel, are primarily located in the planet's core, which is divided into a solid inner core and a liquid outer core. The mantle, situated above the core, also contains denser materials like magnesium and silicate minerals but is less dense than the core. The crust, which is the outermost layer, is composed of lighter materials, primarily silicates. Thus, the distribution of heavier elements is concentrated in the inner and outer core.
