Answer:
Answer 1 :The difference in temperature in the mantle accounts for the density of rocks. ... The core consists of extremely hot metal layers instead of rock. Iron and nickel make up the outer section of the core, while the interior is almost entirely iron. The inner core is almost totally solid and shaped like a ball.
Answer 2:Exact same chemical formula, but with vastly different properties. The mantle is much thicker, nearly 3,000 km thick, while the crust is on average about 40 km. ... A small section of the upper mantle, the asthenosphere, is partially molten, allowing for the movement of the crust as tectonic plates.
