I keep hearing RE'ers say there are mountains of proof that the earth is round... So, what proof exactly? And dont post some secondhand photoshop picture. I mean actual proof.
Mountains are explained in modern science as a phenomenon of plate tectonics. Mountains are created as a result of the expansion of the Earth's crust. New crust is continuously being created as the Earth's plates are created by magma pushed out of geothermal trenches far underneath the ocean surface.
Mountains are actually created as a result of one plate slipping beneath another as it forces its way back into the mantle. At these plate boundaries, buckling occurs on the overlapping plate, and it is actually pushed upwards by the immense amount of force exerted by the two plates.
This could not occur in the FE model, because if the earth was flat, plate expansion would cause the Earth's plates to expand outwards from the "center", which in this case is the north pole. In a spherical (read: RE) model, all of the Earth's plates are constantly exhibiting forces on one another, causing many geological events such as earthquakes, creation of new volcanoes, and creation of mountain chains.
Tension will relieve itself in the easiest way possible, and this would hold true in the Earth's plates. In the FE model, mountains would either fail to exist entirely or be very very small as a result of the almost no tension between the plates; they could expand outwards with little to no resistance. In fact, unless FE theory posits an alternative to plate tectonics, the Earth's surface would be expanding outwards and would never stop. There would be no subduction of one plate under another, so the earth would expand infinitely. This would cause a serious problem for FE theory, because the Earth's circumference would continually expand and the Ice Wall would need to expand with it - I don't see any explanation of this in the FE texts.
