Explanation:
Detailed explanation-1: -Heat conduction: Heat conduction is when thermal energy is transferred from one molecule to another due to the difference in their temperatures.
Detailed explanation-2: -From the geothermal gradient it is also obvious that the outer core/mantle boundary is a big insulater. Since these two are separate heat transfer from the outer core to the mantle is also mainly by conduction.
