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
The Defence of Rorke's Drift having fought in the battle from Lady Butler's sketch of him taken at Portsmouth among the other survivors; his name has subsequently been added to the roll of those who fought at Rorke's Drift. The Defence of Rorke's Drift The Defence of Rorke's Drift is an 1880 painting by Elizabeth Thompson, Lady Butler depicting the 1879 Battle of Rorke's Drift which took place during the Anglo-Zulu War of 1877 to 1879.
