The generalised dynamics which cause a star to deviate from a perfect
sphere may also be applied to the Earth's molten,flexible and rotating
interior.

The correlation between Equatorial speed and deviation from a perfect
sphere relies on the dynamics of differential rotation where the
composition does not rotate as a single unit but reduces unevenly from
Equator to pole -

The generalised dynamics are that for a given composition and
viscosity,the greater the difference between Equatorial speed reducing
to zero at the poles the greater the deviation from a perfect sphere.

The same generalised principles can be applied to the Earth's interior
with the added insight that differential rotation supplies the
mechanism which generates the ridges and causes the crust to evolve
and move.

Oriel36,

Thanks for this useful information. For a while, I was worried that you got
lost in the Spooge Flood, or maybe you created the Spooge Flood?
Nevertheless, it is good to see that you are back and are posting again here
in SAA. Welcome Back!

You're joking, right?

Thank you,

If the generalised dynamics can be applied to the Earth's interior it
would provide a more satisfactory mechanism for crustal motion and
evolution than 'convection cells' insofar as differential rotation
becomes a common mechanism that binds the planet's shape with crustal
motion.

Researchers already know the correlation and I believe they will
eventually apply it to the Earth's interior dynamics as a matter of
course.

For posting this nut's text in full you ought to get the PLONK.

It is not a "nut"; it is a "bot" or "software program" and a rather
entertaining one at that! :-)
It is most likely an Software Engineering AI experiment gone bad and the
student should get a failing grade. Nevertheless, it is entertaining and
that's all that counts.

Anyone who enjoys the video of stellar comparisons in shape would
enjoy applying the same dynamics to the Earth's interior and its
shape,the correlation being due to the uneven or differential rotation
between Equatorial and polar regions in the molten,flexible and
viscous interior.

God forbid any of you know the horror of seeing the enjoyable
correlation ignored because I proposed it and especially because
differential rotation also provides a more productive dynamic for
crustal motion than 'convection cells'.


Contemporary 'astronomy' is like a pyramid perched on its apex,a
highly unstable entity and all based on a single error created by
Flamsteed,I do not fault the man beyond he was seeking terrestrial
longitudes via the Ra/Dec method nevertheless the conceptual monsters
built on the error now surface as the inability to make the neccessary
correlations between astronomy,geology and climatology.

You do not like what I said about the generalised dynamics as it
applies to the Earth's interior and there is nothing I can do about
and that is fine but is it now a requirement to make some silly
statement when silence is good enough of an insult.
