Question

What was the main reason scientists divided Earth's core into an outer core and an inner core?

Answer 1

Answer: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.
