Is the crust solid, or fluid, or something inbetween? I seem to remember reading that the pattern of the rise and fall of... er, I forget the term, mountains that result from plate collisions rather than intrusions... anyway, ISTR reading that the rise and fall of the Himalayas and Alps and so forth look very much like a really viscous fluid when viewed on geological timescales.
Or was the thing that told me that wrong?
(Something tells me that the actual answer to this may be more materials science / physics than geology, but hey, any insight welcome :-))
ETA: Incidentally, I'm guessing that the answer to your first question is relevant to my field... :-)
