Explanation / Answer

23. Answer: C) outercore

Explanation: The earth outercore is in liquid form of nickel iron metals. The rotating liquid outercore causes production of conventional currents in the liquid core. These conventional currents causes magnetic fields and they are passes through the metalic ions. This process is a continous cyclic process and the self existing loop is called dynamo.
