Is it possible that a planet's core could cool just enough to have the plate tectonics stop working without compromising the ability of the magnetic field to block off cosmic rays? I apologize if this question is in the wrong category, specifically I'm looking for the answer based on Earth or an Earth-like world.
By plate tectonics stopped working I mean that the tectonic plates stop drifting because the currents in the mantle are no longer as fluid as they are. I want to know specifically if the magnetic field in this scenario would still be strong enough that Earth or Earth-like planet would be able to support life.
