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
Society for the Study of Black Religion The group chose the name "religion" rather than "theology" to avoid the constraints imposed by the narrower term. Charles Shelby Rooks, who would later become the first African-American head of a traditionally white-led seminary at the Chicago Theological Seminary, took a leading role in the founding and served as the SSBR's first elected president.

It is dedicated to "scholarly research and discussion about the religious experiences of Blacks." The SSBR was
