Thanks KoRn!
...may explain relatively rapid pre-historical changes in sea level that occurred without the typical waxing and waning of the polar ice sheets, which hold and release water on scales of thousands and millions of years. This unexplained sea level rise is one of geology's oldest mysteries.
There are also subterranean seas, basically big caverns filled with huge amounts of water.

Hey Civ; seems there was an article/thread posted last year wherein someone theorized that large chunks of subducted crust, or maybe even chunks of mantle 'more solid than yer average blob of mantle' were prone to being thrust upward and thereby, in very short order, create mountains or mountain ranges. Time frames on the order of days or weeks instead of centuries or millennia. I found it interesting since I'm not automatically inclined to accept the uniformitarianism/gradualism theories at face value any way.
When you get a free minute or two, might you be able to run it down?
