Again, this is Professor El Naggar’s opinion and a confusion of cause and effect. | Again, this is only Professor El Naggar’s opinion and a confusion of cause and effect. To date, no one has provided the scientific evidence derived by Professor El Naggar or anyone else to prove mountains actually stabilize the lithospheric plates. | ||
The available scientific evidence is that the continental plates are stabilized by craton keels. These are deep (60-300km) extensions of cratons into the mantle (far deeper than mountain roots). The formation of these craton roots or keels are unrelated to mountain formation.<ref>Jordan, T. H., Nature, 1978, 274, 544–548; Elasser, W. M., in The Application of Modern Physics to Earth and Planetary Interiors (ed. Runcorn, S. K.), Interscience, New York, 1969, pp. 223– 240; Morgan, W. J., J. Geophys. Res., 1968, 73, 1959–1970</ref> | |||
In fact, cratons are stable regions of the earth's crust that are no longer subject to mountain building processes. These craton roots or keels were formed by 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. isostacy {of the crust, not mountains} at work). <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> | In fact, cratons are stable regions of the earth's crust that are no longer subject to mountain building processes.
