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
Ice Age: Continental Drift are some visually inventive high points." Simon Brew, writing for Den of Geek, gave a very positive four-star review, saying that "not only is "Ice Age 4" arguably the best in the franchise yet, it's also, a little surprisingly perhaps (given that it's a fourth movie in a franchise, turned around on a strict cycle), turned out to be thoroughly, thoroughly entertaining family blockbuster."
