Some Problems of Geodynamics

Abstract

THIS book consists of a number of discussions of important questions of geophysics. The nature and bearing of these will be best understood if we cast a rapid glance at the modern historv of the subject. Fifty years ago the theory of the constitution of the earth was generally regarded as complete, in the sense that almost everything was thought to be known that was in the nature of things ascertainable. The external shape and the distribution of density in the interior were assumed to be such as are consistent with primitive, or indeed with present, fluidity (except for a superficial crust); and a certain reasonable law of density, viz., that of Laplace, was regarded as, if not actually demonstrated, at all events highly probable. The theory was a monument of mathematical skill, and had indeed evoked mathematical methods which had proved to have an ever-increasing value in other fields; but as a speculative mine it was held to be practically worked out.
