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
Drift (Transformers) Drift believes that Bumblebee is not a worthy leader, although they work very well in battle and Drift uses his chopper mode to lift Bumblebee to save Cade Yeager during the Autobots' raid in KSI with Attinger. During the battle in Hong Kong, Drift rides the Dinobot into the fight after helping Optimus free the Dinobots. Afterwards, Optimus Prime orders him along with the other Autobots to protect the Yeager family before he departs for space.
