Well, I do digress with my first post in this thread - the water will indeed rise (especially as the land masses further rebound in places like Greenland), eroding coastlines as a result, but there has to be balance somewhere.
Is it rather interesting how the average depth of oceans is around 18,000 feet (over 70% of Earth's surface area is water), and then there are land masses "popped" right up - like as if by design?
At 18,000+ feet, imagine the pressure of water - compared to the upper mantle. Like, there's lots of oil and stuff underneath, and water as well.
Wouldn't billions of years have already "smoothed" the Earth over, so that there's like 12,000 feet of water covering the entire Earth - after all the landmasses have been eroded by wave action, rain and glaciers (powerful enough to carve out mountains), earthquakes, etc...
