Continental drift is created at spreading centers, and this, along with subduction, drives the system of plates in a chaotic manner, resulting in continuous orogeny and areas of isostatic imbalance. The theory of plate tectonics explains all this, including the movement of the continents, better than Wegener's theory. Hans Stille and Leopold Kober opposed the idea of continental drift and worked on a "fixist" geosyncline model with Earth contraction playing a key role in the formation of orogens. Other geologists who opposed continental drift were Bailey Willis, Charles Schuchert, Rollin Chamberlin and Walther Bucher. In 1939 an international geological conference was held
Canadian Society for the Study of Rhetoric Canadian Society for the Study of Rhetoric The Canadian Society for the Study of Rhetoric (CSSR) is a bilingual scholarly society based in Canada that is open to scholars involved in the teaching or researching of rhetoric.

Its membership typically includes scholars from North America and Europe (not just
