As above, there is no scientific evidence which demonstrates that mountains stabilize the lithospheric plates, and El Naggar provides no references. By contrast, there is scientific evidence that suggests that continental plates are stabilized by craton keels. Craton keels are deep extensions of cratons into the mantle which extend any where from 60-300km below the surface. These keels extend far deeper than mountain roots. The formation of these craton roots, or keels, is, however, unrelated to mountains or their formation.<ref>Jordan, T. H., Nature, 1978, 274, 544–548; Elasser, W.

Critics also point out that cratons are stable regions of the earth's crust that are no longer subject to mountain building processes. These craton roots or keels form through the depletion of basaltic elements into the asthenosphere, leading to less dense material that sinks deeper into the mantle due to the lower buoyancy (i.e. the isostasy of the crust, rather than the mountains). <ref>Sankaran, A.V. - [{{Reference archive|1=http://www.ias.ac.in/currsci/nov102001/1158.pdf|2=2011-10-02}} CURRENT SCIENCE] - VOL. 81, NO. 9, 10 NOVEMBER 2001 pp. 1158-1160</ref> | |||
