Pre, somewhere in one of the threads relevant to this discussion you suggested a parallel between current crustal movement and isostatic recovery. Returning to this though; I find myself wondering why, if current tectonic movement is the result of past expansive forces, are there areas in which there are converging tectonic segments? Cf. Lithgow-Bertelloni and Richards (1997).
"are there areas in which there are converging tectonic segments"
The collision caused compressive forces. The expansion caused expansive (tensional) forces.
So there must be some converging tectonic segments (caused by the collision), but most segments are diverging (caused by the expansion of the planet).
Pre, do you interpret their (the "scientists") lack of answers as evidence that they have no answers?
Of course.
