ORBITAL CONSEQUENCES. “This may have generated torques and frictional heating that caused not only development of an asthenosphere, enabling plate tectonics, but also influenced convection in the outer core. This in turn enabled differential core motions and development of an inner core and internal strong dipolar magnetic field for the first time, shielding Earth’s surface from solar-particle bombardment and enabling evolution.”
