Structural and dynamical guidelines for discussion

Regardless of the nature of a celestial object,be it a star,planet or
moon, the densest material exists at the core and becomes less dense
the further it exists from the core,sometimes going through a
transition of states such as the transition zone between the ocean/
atmosphere and the rotating molten interior,this zone is made up by
the Earth's fractured crust ( less dense than the interior/denser than
the liquid oceans and atmosphere.There may be some objections to the
oceans considered as seperate from the crust amnd allied with the
atmosphere in terms of being a planetary layer but that is left open
for discussion.

Stars of a given size and composition will often vary in shape
depending on maximum Equatorial speed -

The binding correlations follow three prime components-
composition,maximum equatorial speed and differential rotation,for
example,a variation in equatorial speed effects shape which in turn
affects differential rotation. of the rotating composition


As our planet is not a perfect sphere and there is a very good
indication that rotational geodynamics is involved in crustal
geodynamics,there is a good opportunity to draw on the lessons and
observations of stellar rotational dynamics and apply them to the
Earth.The neatest feature is that the differential rotational shear
bands provide a better mechanism for crustal motion that geostationary
'convection cells'. The point of discussion here is whether rotational
geodynamics is more productive than geostationary 'convection cells'.


Plate tectonics appears to have stalled as an excellent concept due to
the weakness of the underlying mechanism of convection cells,a concept
that does not require any reference to a rotating Earth or its oblate
shape.Plate tectonics looks far better from a rotational geodynamical
standpoint by virtue of linking planetary shape and crustal dynamics
under a common rotational mechanism.The real discussion is how to
organise the interior composition to satisfy the 40 km deviation with
the energy rquired to move the surface crust.In terms of a bowling
ball,the surface crust would only account for a millimetre of so
compared to the diameter of the ball so it is no stretch to consider
that the 40 km deviation has a far more powerful rotational mechanism
than that needed for plate tectonics.

Forging closer links between astronomical dynamics and geological
evolution is not such a huge leap,most people already know that
rotational dynamics alters the profile of the planet and the fractured
crust moves along this less than spherical profile.I can put it down
to something that has yet to occur to people in applying genralised
rotational principles to a celestial object in a flexible/molten
state.It is also highly enjoyable to cross over between astronomy and
geology.
