The crust acts as an . This means that it helps block the from the core from reaching the surface . The crust is not a conductor or transmit heat from the core . The surface of the Earth is warm due to NOT from the radiocative . The core also produces a . This helps protect Earth from much of the radiation from the sun that is harmful . The mantle contains . These are circular items that work by transferring heat within Earth's . This occurs because hot , rises . As this plastic rock rises towards the surface it begins to as it moves farther from the nuclear core . As it cools it becomes until finally it toward the core again to begin the process again . The core is the for convection currents .
