...a three dimensional planet, ..a whole lot of stuff that organised
itself into a great big lump, from mass that we know is made up of
subatomic particles (that spin like billy-O! - is that right? Do
sub-atomic particles spin?) (and why?). Until we can answer the
question at what point subatomic mass particles and electromagnetic
force bow out as a property binding mass, and gravity (whatever
*exactly* that is) kicks in, and how it all behaves under the
pressure temperature conditions of the Earth's interior, it seems to
me we are not in a position to even remotely broach the question of
understanding the mass of the planet, either its aggregation and
formation, or its deformation. To me, the accretion theory is the
astrophysical equivalent of subduction, no more. All we *can* do is
look at the two dimensions. But that doesn't mean we should accept
that;'s all there is. Plate tectonics is grossly inadequate, and
doesn't work, not even by its own measure. And if there's one thing
we do learn from geology it is that *a map is a section*, and the
Pacific and the Atlantic (with their continental margins) provide us
(+ve -ve +ve -ve, ...and with 'palimpsests') with thousands of
kilometres of opportunity to investgate sections down through the
mantle that plate tectonics would forever ignore in its facile Mickey
Mouse model (that doesn't work).

(Ah yes, ...but it works for you... / "If it ain't broke don't fix
it...." Mmm? Head in the sand, Carsten. (I bet you've never
thought about plate tectonics before this....)
