Nuclear fission occurs naturally all the time. Heavy elements such as Uranium and Thorium continuously undergo slow, spontaneous fission that generates radioactivity and heat. This heat warms the planet’s crust and molten core. The rotating core generates the magnetic field that protects all life from deadly cosmic and solar radiation. Heat from radioactive decay is also thought to drive plate tectonics.
