===Mountains | ===Mountains and isostatic stabilization=== | ||
This is | Advocates of the miracle point to George Airy's model of isostasy, which supports the idea that isostasy occurring below mountains causes mountains themselves to be more stable than if isostasy were not occurring below. This, they argue, is another point of evidence that mountains stabilize the Earth as described in the Quran. Critics respond to this argument by stating that George Airy's model says nothing special of mountains, per se, and simply demonstrates that isostasy - that is the extension of the earth's crust below the surface to a degree correlated to the height of the surface at any given point - generally causes the crust of the earth to be stable, whether or not a a given area is mountainous. Moreover, they point out, the fact that a mountain's isostasy causes the mountain to stabilize 'itself' - that is, just as the isostasy of any region causes that same region to be stable - does not mean that the mountain is in any way stabilizing the Earth in general or even the surrounding region in any meaningful way. They summarize this counterargument by suggesting that, on the basis of Airy's model, it can be said that if there were a region possessing a mountain and subject to isostasy, there is no reason to believe that region would be more stable than another, similar region that did not have a mountain but was also subject to isostasy to the same, natural extent. | ||

Another way the critics put it is that the phenomenon of isostasy is itself responsible for the stability of the crust - whether or not the crust is host to mountains in any given region. Isostasy stabilizes mountains, even terrain, and even indented regions on the Earth's surface. The Mountains do not cause this isostasy any more than isostasy causes mountains, as isostasy is co-occurrent with any variety of terrain - mountainous or otherwise. The co-occurrent isostasy is, however, responsible for the stability of the mountains as well as the crust, and not the other way around - that is, a region excepted from the norms of isostasy (as many are) will not be as stable, whether this region is mountainous or not. Isostasy is best understood as a phenomenon separate from the mountains altogether, as it is no more bound in the simple fact of its existence to the presence of mountains than it is to region of simple, flat crust (even if the specific form it takes in either of these cases is). | |||
=== | ===Earthquakes and the meaning of ''tameeda''=== | ||
When shown evidence that collisional-type mountains are associated with earthquakes some Muslims will then claim that the Qur'anic verses do not refer to earthquakes at all. They will claim that tameeda also means stagger, roll, sway, or tilt, and that there's significant difference between them and the short sharp shock of an earthquake (i.e. tameeda refers to some phenomenon, assumed to be associated with geological timescale, that is presently unknown to and undefined by our present understanding of geological science). | When shown evidence that collisional-type mountains are associated with earthquakes some Muslims will then claim that the Qur'anic verses do not refer to earthquakes at all.
