Based on observations (there are roughly 50 independent observations that support the assertion) plate tectonics is driven by liquid CH4 that is extruded from the liquid core of the planet as it solidifies.
That assertion is consistent with the analysis of wave velocity which shows there must be light elements in the liquid core (roughly 5 %, the liquid is roughly the size of the moon) and theoretical analysis for the liquid core that shows CH4 can «dissolve» in the liquid core and would be extruded when a portion of liquid core solidifies.
The forced movement of the super high - pressure liquid CH4 from the liquid core and drop out of the organic metals at specific pressures explains why there is heavy metal concentration in the crust of in some cases a million times more than the mantel.
