Answer:
True
Step-by-step explanation:
True. The processes that reverse the polarity of the Earth’s magnetic field are indeed related to changes in the flow of the iron-rich liquid in the outer core. The Earth’s magnetic field is maintained by rapid motions of this conductive fluid. As the core moves, the magnetic field lines are stretched and twisted, and a new magnetic field is created. This can lead to a reversal in the polarity of the magnetic field.
