Observations of a fast flowing stream

Looking out from the Irish coastline and the powerful waves that crash against the shore and cliffs there is very little indication of what happens 1500 miles to the West and at great depths beneath the Atlantic. Walking along a beach one day after a thunderstorm, I stopped at a fast running stream looking for a narrow place to cross it,something similar to what is seen in this borrowed video -

Watch in the bank being eroded by the stream was fascinating given that I had already been working on zonal flow acting on the Earth's oceanic crust and a lag/advance mechanism for crustal generation at the Mid Atlantic Ridge.. It occurred to me that the very mechanism which creates oceanic crust at one side of the ridge also erodes and destroys oceanic crust where one plate dives beneath another.

That elegant 'S' shape the splits at the Equator and basically runs up and down the rotational spine of our planet really is more suitable for the mechanism for plate tectonics than the old stationary Earth 'convection cells' notions which simply can't compete.

Like most things it is the lack of astronomers that prevents this more productive if speculative view to take hold insofar as what astronomer could possibly exempt the Earth's viscous interior,at least that fluid in contact with oceanic crust, from the uneven rotational gradient seen in all fluid objects with exposed fluid compositions. What is especially lovely about evolutionary geology and rotation is that the lag/advance mechanism fits neatly with the less than perfect spherical shape of our planet.
