To argue for a geostationary 'convection cell' mechanism  for crustal

material  below the crust insofar the the motion of the crustal plates
depends on the medium and the motion of that medium.

Taking the responses of particpants here as a gauge for geologists and
dynamicists in generaL ,it appears that the option of a geostationary
Earth is preferable to a rotating one and in futures they are
constrained to organise the internal composition of the Earth around
'convection cells' without any reference to rotational dynamics and
the Earth's shape

There is an option to look at stellar dynamics and apply the
correlation between Equatorial speed,differential rotation and
deviation from a perfect sphere as a common bond where one indicates
the presence of the other two components as a general rule -

If 'convections cells' remain established as a 'fact',plate tectonics
is finished or becomes a  counter-productive concept that will prop up
a geostationary Earth view.

We're well aware of how the sun, a gaseous body, undergoes differential
rotation. What's not clear is how that is supposed to apply to the
Earth, which is a zillion times more viscous. You're free to come up
with experiments and equations that describe how viscosity affects
convection and differential rotation on Earth. To begin with, I'd like
to see equations of the form presented in this Wikipedia article:http://en..wikipedia.org/wiki/Solar_rotationwith coefficients adjusted
for Earth. Pleaser also show your data. And thinking should be a little
more advanced than "Well, the sun does it!"


Well, considering that you have 'convections cells and differential
rotation occuring on Earth simultaneously,I think even the 'sun does
it' would look advanced to you. I enjoy the work that stellar
dynamicists are doing with stellar shape arising from rotation and
simply apply the gneralised principles to the Earth shape and
rotation.

You are enitirely free with supportive ,equations and all,to remain
with your geostationary convections cells insofar as,it spares me from
wasting my time.The rub is that you cannot speak of planetary shape
without discussing differential rotation let alone the implications as
the underlying mechanism for crustal motion and although you may be
slow on the uptake,you will probably eventually get that you are stuck
in a geostationary position in all aspects one way or another.

People like the transit of continens because they can see the
geographical relationship,especially between S.America and
Africa,likewise they will have no trouble gauging how the rotation of
the Earth supplies to mechanism for crustal motion by looking at how
other rotating objects behave -

As for non geometric equations,well that garbage is too vague to be
anything useful and has destroyed structural astronomy for the last
few centuries.Evolutionary geology does not and never has needed the
mathematicians foil so many here can speak freely about the
rotational dynamics that you have an aversion to.





Good luck to you.

The 'convection cells' mechanism for crustal motion is a
geostationary notion and requires no reference to planetary shape and
rotational dynamics therefore you are constrained to make what you can
out of your stationary Earth model and it spares me the time having to
explain the complexities of using differential rotation to generate
planetary shape and from there into evolutionary geology.
