To Brian

Didn't I tell you to zark off once already?


You are the freak who believes in convection cells as a mechanism for
crustal motion.

Why is it that pseudoscientists must always resort to such childish
name calling when someone calls their cards?


You are a freak who believes that convection cells are the mechanism
for crustal motion,this is not an offensive statement but roughly
correct given that you have a real mechanism in differential rotation
bands in front of you.



Go study fluid dynamics and observe that rotating fluid/gas celestial
objects display both differential rotation and an Equatorial bulge.

The equatorial bulge is nothing more than the result of centrifugal
forces acting on a spinning body.


Centrifugal forces,yeah,yeah yeah,this has been the story for hundreds
of years and it will tell you why the Earth and all rotating celestial
objects are spheres but it is useless to explain deviations from a
perfect sphere.

I wonder if there are any other bright sparks who can grasp this easy
to understand and observable principle.




As the only person alive to recognise

That tells a lot. Have you given any thought as to why you and only
you have recognised this supposedly important fact? Are you special
in some way?


Perhaps you are the one who is special for it takes quite an effort to
miss the shape of the Earth as a geological feature.Unless you live in
a cave you would know that the Earth's fractured crust is composed of
plates that are subject to rotational forces in the plastic-molten
mantle.As all rotating celestial objects display both differential
rotation and a bulge,it takes quite a special person to ignore it.

that the Earth's deviation from a perfect sphere

The Earth deviates from a perfect sphere by less than 3/10ths of
one percent. Other planets in the solar system are more oblate
than the Earth.


constitutes a geological feature I have no problem
working out exactly what Newton only guessed at.The uni-directional
differential rotation bands running in great rivers in the
fluid-plastic mantle generate the Bulge,supply the evolution of new
crust and partialy influence terrestial surface features.

Mars exhibits an equatorial bulge 2.2 times larger than the Earth.
If the bulge is caused as you say, then why does Mars not exhibit
"terrestial [sic] surface features" similar to, nay, more extant
than on Earth? Having a larger equatorial bulge implies - using
your theory - differential rotation bands of greater magnitude
than on Earth. If these motions are so much greater, why is Mars
so geologically "dead"?


The composition of the mantle changes from planet to planet as does the
rates of rotation.If you wish to argue differential rotation bands out
of existence in order to keep convection cells as a mechanism for
crustal motion then be my guest.

Btw,it is not a theory,the shape of a rotating celestial object will be
a sphere,a deviation from a perfect sphere (and 40 km is not small
deviation over the total shape of the Earth) can be ascertianed from
observing uni-directional differential rotation bands.




It would be nice if the geologists started to recognise the largest
terrestial feature of all - the shape of the planet.

As for you,stick with your midget minded convection cells and your
stationary Earth ,if any person wants to observe what differential
rotation bands look like they can take it from the Sun -

http://www.astronomynotes.com/starsun/sun-rotation.gif

The Sun is a plasma/gas. The earth is a solid/liquid. Let's
compare apples to apples, shall we?

Oh, by the way, the Sun's equatorial bulge is over 300 times less
than the Earth's. Yet it exhibits far more of your "differential
rotation bands" than the Earth does.


Geologists should have a ball adjusting the composition and densities
in the mantle to suit both the Equatorial bulge and to give crustal
evolution and motion some teeth.



Differential rotation bands in the fluid-plastic mantle cause the Earth
to deviate from a perfect sphere because to imagine otherwise is to
make the Earth and exception.

Hmmm...the Sun exhibits differential rotation bands to a far greater
extent than the Earth. Why then is the Sun's equatorial bulge 373
times SMALLER than the Earths? If differential rotation bands "cause"
the equatorial bulge as you claim, why is the Sun's so much smaller
than the Earth's?


Composition, densities,rate of rotation ect.




I could not give a damn if you understood
the principle or not,as far as I can see you intellectual midgets do
not know what to do when encountering common sense
descriptions,astronomical,terrestial and bottom line.

Again with the childish name calling and ranting. Is your position
so weak that you can't defend it otherwise?


I am especially proud of the differential rotation bands as a mechanism
for both bulge and crustal motion,at least partially responsible for
terrestial surface features.I never imply that there is a desperate
need for a mechanism but anyone who approaches the new mechanism will
find it almost impossible to return to convection cells/stationary
Earth.

It is not my fault that everyone is intent in shooting themselves in
the foot with the 'scientific method' when simple intution will
do.There are so many avenues open when people leave the empirical
mantras and this just happens to be one avenue among many that is
ignored.
