What is the difference between the inner and outer core?

Core–mantle differentiation is the set of processes that took place during the accretion stage of Earth's evolution (or more generally, of rocky planets) that results in the separation of iron-rich materials that eventually would conform a metal core, surrounded by a rocky mantle. According to the Safronov's model, protoplanets formed as the result of collisions of smaller bodies (planetesimals), … Web22. jul 2024. · The inner core is solid the outer core is liquid and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core silicate crust and mantle) and the increase in temperature and pressure as depth increases.
