The proposal of differential rotation across latitudes on a rotating planet was introduced into this newsgroup around 20 years ago based on the principle that all rotating celestial objects with a viscous composition, even the Earth's atmosphere or the Sun's plasma, demonstrate this feature.

The exemption of the Earth's interior from this dynamic feature is as astonishing as it is dismaying considering the clues on the fractured surface crust signifying the actions of the fluid motion in zonal flows (differential rotation).

The Earth science of geology suffers from the same narrow and inclusive subculture as the Earth science of climate, however, the issue here is developing a more definite possibility that zonal flows across latitudes influence crustal evolution and motion along with the 26-mile spherical deviation between equatorial and polar diameters.

I know why there has been no movement on this topic in over two decades and the heart sinks sometimes in knowing that it is a self-inflicted wound on individuals and humanity.

I often check up to see if anyone has an appreciation of celestial objects with fluid compositions and the mainstay of differential rotation across latitudes. The effects on the Earth's fractured crust have already been determined and especially the Mid-Atlantic Ridge and the symmetrical generation on either side of that ridge which follows the Earth's rotational axis.

The linkage between the differential rotation of the fluid interior with the entire length of the Mid-Atlantic Ridge or the relationship between zonal flow and fracture zones is enjoyable irrespective of the dubious ability of researchers to ignore it-

Of course, the gas giant is not the same thing as the Earth's fluid interior yet almost impossible to impose convection cells where differential rotation should be expected! I am still excited to identify a lag/advance mechanism across latitudes which would generate the necessary symmetry along with paleo-magnetic signatures left on the crust.

Then there is the spherical deviation of the planet which follows the same differential rotation principles using planetary comparisons with our sister planet Venus which also lacks plate tectonics.
