WebGoing against this, the Moon and Mars have stagnant lid convection systems while Earth has an active plate tectonics system. However, that our Moon still has a liquid core has to argue against the the Earth's core freezing any time soon. One key to answering this question is the rate at which heat energy crosses the core-mantle boundary. Web(a) solid iron inner core, molten iron outer core, rocky mantle, lighter rocky crust 6.
