Default Crustal dynamics

The proposal emerged in 2005 via and another newsgroup that the 26 mile spherical deviation between Polar and Equatorial diameters and the Mid Atlantic Ridge could be bundled together using a common mechanism, namely, differential rotation across latitudes.

Astronomers are supposed to recognise that when a viscous celestial composition is rotating, it has an uneven reduction in rotational speeds between its maximum speed down to zero at the Poles. When this differential rotation mechanism is coupled with a solid but fractured crust that does have an even rotational gradient between Equator and Poles then it would account for the fracture zones across the length of the Earth and coincident with the axis of rotation -

Rotation as a mechanism did show up shortly after the outlines of a mechanism was proposed but it was and remains so haphazard that it may as well have remained with the older and non-rotational view in circulation around the time this newsgroup was seeing the first outlines of differential rotation -

I see a few pseudo-intellectual strutting around this newsgroup still and completely oblivious to innovations that some in the wider world have taken notice of and especially the partitioning of direct/retrogrades and to a lesser extent this topic.

The only means to account for the symmetrical generation of Oceanic crust either side of the Mid Atlantic Ridge along the entire length of that geological feature is the relative speeds of the zonal flows across latitudes so although the maximum Equatorial speed of 1,000 mph reduces unevenly to the zonal flow beneath it, the same applies all the way to Polar latitudes. The fractures zones are clues to the lag/advance mechanism which creates ocean crust either side of the ridge while 'convection cells' are simply untenable.

The dynamics behind the 26 mile spherical deviation between equatorial/polar diameters is many magnitudes greater than individual effects on crustal plates and their evolution but these forces, as per differential rotation, act perpendicular to the axis of rotation rather than the ungainly* notion that the forces act from the center of the Earth.

One of the outstanding clues is also the Drake passage and the Antarctic Continent itself and its near circular shape -

Considering that I haven't been aggressive demonstrating the possibilities over the past 15 years and it is one of these topics that allow for a generous speculative approach, the scientific community look like deer caught in the headlights or are still pulling a Wegener stroke but more likely are just dull and dour theorists unable to work with the effects of the planet's motions. In this day and age it just looks silly rather than something to complain about.

It's not silly when three buses pass on other side of the road but we must always wait half an hour for ours to arrive.

Differential latitude velocity stinks!
You can't have your crust on your pie and eat it.

The signatures of lag/advance mechanism arising from differential rotation of the fluid interior across latitudes where oceanic crust is being developed perpendicular to the rotational axis is a striking feature where astronomy and terrestrial sciences intersect.

By lag/advance I mean that the uneven rotational gradient is a product of zonal flows much like the Sun or gas giants display zones where the period rotation is unequal -

For evolutionary geology purposes, a inequality has to exist between crust and fluid insofar as both cannot rotate as one unit and besides, it is nearly impossible to exempt the Earth's viscous state beneath the fractured crust from differential rotation. It is unusual that researchers would exempt the Earth from a principle that is observed in all planets which display less than a solid structure be it atmosphere or plasma.
