WebFeb 17, 2012 · Ghosh and Holt (p. 838) present a global geodynamic model that achieves a high level of accuracy in fitting surface plate motions, plate boundary deformation, and intraplate stress fields. The model identifies regions where mantle drag drives plate motion and regions where the drag resists plate motion. Based on the relative magnitude of … WebSummary. The theory of continental drift was the first step toward plate tectonic theory, which became the foundation upon which modern geology is built. This module describes how the work of Alfred Wegener, Harry Hess, and others led to our understanding of plate tectonics. It explains plate tectonics as the driving force behind ongoing ...
