The schematic diagram taken from page 220 of ''Anatomy of the Earth'' by the French geologist Cailleux is cited by various sources advocating the reality of the proposed miracle.<ref name="A Brief Illustrated Guide to Understanding Islam">[http://www.islam-guide.com/frm-ch1-1-b.htm A Brief Illustrated Guide to Understanding Islam/ B) The Quran on Mountains] - Islam-Guide.com, accessed October 1, 2011</ref> The basic underground protrusion of the crust beneath the mountainous region of the Alps, for instance, appears as a sort of peg embedded in the lower layer of the Earth.

This term describes the nature of the Earth's crust such that the height of the crust above the layer of the Earth immediately beneath the crust tends to be proportionate to the depth of the crust into the lower layer in the same area. | ||
Thus, elevation above sea-level tends to correlate positively with the thickness of the Earth's crust at any given place. The reason why the crust tends to exist in this manner is compared to the same physics of floatation whereby the majority of an iceberg suspended in water extends below sea level and, at the same time, it is the case that the taller the portion of ice above sea level, the deeper the iceberg dips down below. | |||
Advocates of the scientific miracle argue that isostasy affirms the peg-like nature of mountains and that Muhammad could not, in the 7th century, have come to realize this without divine aid. Critics respond to this by arguing that the caption associated with the diagram found in Cailleux's book explicitly points out that the visual representation has had its 'vertical scale greatly exaggerated'.<ref>Click [[:File:Anatomy of the Earth- Cailleux- pp 220-221.jpg|here]] for a more complete view of the page scan.</ref> As a result, critics argue, the peg-like nature of mountains is not so plainly evident as the exaggerated representation found in the diagram would make it seem. | |||

Other visual representations with less exaggerated and more accurate vertical scales, some of which are cited by the advocates themselves, do not depict mountains as so plainly resembling pegs.<ref name="A Brief Illustrated Guide to Understanding Islam"></ref> Advocates respond by suggesting that when viewed in this more accurate representation, the mountains resemble 'blunt pegs'; critics disagree.

Critics hold that the 'roots' of the mountains described by isostasy do not resemble pegs in either form or function. For instance, isostasy, while often observed, is by no means universal and there are several outstanding examples of mountains and other elevated geological structures which have no such roots. | Critics hold that the 'roots' of the mountains described by isostasy do not resemble pegs in either form or function.

Examples include structures formed by the geological processes of extension and faulting, such as the Nevada Basin and Range, as well as those formed thrust and fold belts, such as the Appalachians, Eastern Bolivian Andes, Zagros Mountains, and the Calcareous Alps.

Another important example is the Andes mountain range, whose 'roots', as observed in a true-scale cross-section of the range, do not resemble a peg and which do not serve any 'peg-like' purpose. | Another important example is the Andes mountain range, whose 'roots', as observed in a true-scale cross-section of the range, do not resemble a peg and which do not serve any 'peg-like' purpose. | ||

Critics conclude that what may at most be said regarding the roots of those mountains that possess them is that they resemble pigs in some minimal metaphorical sense and that it is not the case that all mountains are literal pegs, as described in the Quran, which have been 'cast down' into the earth in order to stabilize this. If the advocates opt to transition to a metaphorical interpretation here, the critics continue, they have made an arbitrary decision, as the relevant scripture appears to take its own description quite literally (as is generally the case with verses in the Quran describing the step-wise creation of the Earth and heavens). | Critics conclude that what may at most be said regarding the roots of those mountains that possess them is that they resemble pigs in some minimal metaphorical sense and that it is not the case that all mountains are literal pegs, as described in the Quran, which have been 'cast down' into the earth in order to stabilize this.
