What really bothers me is the fact of those triangular shapes of most
of the continents and why they all have the same orientation.
Nobody could explain that yet


Try a Google search for * "continental drip" * .


That should be continental drift as the planet's geological evolution
relies heavily on the difference between continental crust and oceanic
crust where the latter comes under the influence of the rotating fluid
interior.Trying to explain the shape of the continents using
centrifugal forces misses the point of the evolution of crust through
spreading centers and especially the Mid Atlantic Ridge which is a
testament to the lag/advance mechanism of differential rotation - a
mechanism known to all astronomers who look at rotating celestial
objects with exposed viscous compositions.

Planetary shape and the 26 mile difference between equatorial and
polar diameters fits neatly in with an uneven rotational gradient by
virtue of planetary comparisons where Venus has no tectonic activity
beyond volcanic while it has no appreciable spherical deviation due to
residual rotation.Turn what way you will,in order to consider a
rotational mechanism which drives the continental crust apart,it must
dovetail with planetary shape and that requires the core fact that the
Earth turns 15 degrees/1037.5 miles at the equator and a full 24901
mile circumference in 24 hours.

It is something else to have worldwide geology departments who cannot
operate with the most fundamental fact of all in that the Earth is
round,rotating and has specific values attached.I have seen them act
like petty thieves in Wikipedia in trying to cobble together a
rotational mechanism like Frankenstein's monster with bits patched
together from here and there instead of the ease of reasoning which
combines plate tectonics with planetary shape using an already
observed feature of rotating fluid dynamics.
