How did density segregation contribute to Earths internal layers?

Answer 1

Density segregation, a process driven by gravitational differentiation, played a crucial role in the formation of Earth's internal layers. As the early Earth heated up, heavier materials like iron and nickel sank toward the center, forming the core, while lighter materials such as silicates rose to form the mantle and crust. This separation based on density led to the distinct compositional layers we observe today, with the core being metallic and dense, and the mantle and crust being more silicate-based and less dense. Thus, density segregation was fundamental in shaping Earth's layered structure.
