The mechanism driving plate motion is differential rotation which also
produces the 40 Km planetary deviation from a perfect sphere.It is
just a matter of borowing principles from rotational stellar dynamics
and apply them in principle to the rotating flexible and viscous
interior of the Earth .

The single mechanism based on geodynamics makes the broad view of
plate dynamics and planetary shape fit together neatly with
differential rotation already established as an observed rotational
principle.

It is one of my favoraite insights Sam arising from the investigation
of the Earth's motions and its affects

Also see Nov 2007 Scientific American article on heating of the earth's
crust and differences correlating with terrain height.

Better still Dennis,the fractured crust profiles the less than
spherical shape of the Earth therefore the motion of the crust from
one planetary profile to another would have effects such as intraplate
Earthquakes and so on as the crust adjusted to a new profile.It is not
such a great leap to have rotational geodynamics drive crustal
geodynamics,after all,the comparitive depth of crust to the molten
interior is very small and given the rotational dynamics which create
the 40 KM bulge,I have no problem adapting the rotational dynamics to
crustal motion and related effects.

Unfortunately,dynamicists seem stuck on a geostationary 'convection
cell' mechanism which requires no reference to planetary
shape,rotational orientation and exempts the Earth from generalised
rules for rotating objects in a viscous state (the interior of the
Earth qualifies),by that I mean differential rotation.

Plate tectonics may actually tell you quite a lot about planetary
rotational dynamics and it would be enjoyable to adjust the Earth's
interior composition and viscosity to suit not only the degree of
spherical deviation but the energy to drive crustal evolution and
motion.Unfortunately dynamicists have organised the Earth's interior
to ignore rotational dynamics in favor of geographically and
geometrically ill-defined convection cells.
