Answer:
The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. ... The metallic nickel–iron outer core is liquid because of the high temperature. However, the intense pressure, which increases towards the inner core, dramatically changes the melting point of the nickel–iron, making it solid.
