  •  The thinner part. . . (2+ / 0-)

    of the question/answer which has been made thicker over time shows there is support for continental mass increasing, yet continents continuing growing and diminishing in size given the millions of years of plate migrations. I met an expert on the field one year, whose name I now stupidly forget, and it was his opinion the whole shebang is about even, a give or take proposition. And I am reluctant to argue one way or the other. But basaltic mass is obviously growing and I'm not sure just which part of the world is doing the biggest growth, but something tells me Iceland. Anyway, I am sure the different processes you mentioned has something to do with no firm answers in the community, albeit there are theories. And here I thought working out the Grand Canyon's "Muddy Creek" problem was the most serious matter to debate. HA! Thanks for posting your illuminating comment, janislav. (I"m still moving this week and Internet service/opportunity is spotty, at best. . .should be back in the driver's seat within a week, I'm hoping. . then I'd like to run a few theories by you and see what you think.)

    Treat the world (yourself, and others) as part of a living organism. Everyone and everything will benefit.
