He does not allow the "crustal relief" to have the upper hand in the matter.
Moreover, in most cases, they are not reversible as are the crustal and solar phenomena.
Professor C. Lapworth has generalized the grand features of crustal relief in a scheme of attractive simplicity.
Geologists would report on the crustal relief (as the features of Mother-Earth are inelegantly termed).
Two kinds of crustal movement, as we have seen, are recognised by geologists.
Like its European parallel, it has been diminished by sedimentation and crustal movements.
Why crustal movements occur is not definitely known though many theories have been advanced to explain them.
The fundamental conception of geography is form, including 620 the figure of the earth and the varieties of crustal relief.
Thus we conclude that while climatic changes and crustal movements usually occur together, they may occur separately.
The dominant forms result from crustal movements, the subsidiary from secondary reactions Geology and land forms.
