It is a pleasant experience to see researchers taking notice of differential rotation across latitudes along with differential rotation within internal layers-

Overlaying the Earth fractured surface crust on this mechanism along with the 26 mile spherical deviation between Equatorial and Polar diameters is an adventure rather than just research.

While Wegener, the first person to reason out plate tectonics by employing different areas of Earth science research, this is extended to draw from solar system observations and then applying common traits of fluid dynamics of objects to the Earth itself in terms of a geological evolutionary narrative.

" Scientists still do not appear to understand sufficiently that all earth sciences must contribute evidence toward unveiling the state of our planet in earlier times, and that the truth of the matter can only be reached by combing all this evidence. ... It is only by combing the information furnished by all the earth sciences that we can hope to determine 'truth' here, that is to say, to find the picture that sets out all the known facts in the best arrangement and that therefore has the highest degree of probability. Further, we have to be prepared always for the possibility that each new discovery, no matter what science furnishes it, may modify the conclusions we draw." Alfred Wegener
