Science And The Bible - Introduction

[Purple Rabbit]

Yes, I suppose I should clarify that.

What I meant was that this idea that the oceans were where the ground was pushed down, and the continents were then left high and dry, does not correlate with geological evidence of continental drift, plate tectonics, and the like. The reason that the continents are higher than the oceans is that basically, the continental crust is of a lower density than the oceanic crust, and the mantle is a higher density than either. So, both of them "float" at different levels in the mantle. So, it is not that the water is "pushing down" on parts of the earth and forming mountains. Mountains are often formed when seismic plates interact and colide, or subduct. The ocean does not affect this, and the process is much too slow to be accounted for by a 40 day period.

You introduce new arguments like higher and lower density but present no evidence for it. Furthermore it seems to me that in the model you present the density alone is not decisive but the total mass is. It's the total pressure on the mantle that's relevant (assumed that there's no upward trust from convection streams in the mantle), i.e. the thickness of the crust in combination with the density of the crust is critical. Furthermore a water column of 10 km does add considerable pressure to the mantle on top of the weight of the crust. You can't neglect it in your model.
