Do we understand that beneath it all is an elaborate system of differential cooling and mineral aggregation and disaggregation - - that the molten core is slowly cooling as the earth rotates on its axis, affecting the spin, affecting the speed of rotation, and above all, affecting the crust, the surface -- how the core cools determines how the convection currents flow through the mantle, and how the crust is subjected to pressure -- suddenly a current of more liquid, more molten mantle passes under a continent -- under enormous pressure, rifting the Atlantic Ocean, where molten lava emerges into the spreading sea floor, or compressing the wrench-faulted California plate, now being re-melted into the core.
