What is Alfred wegner 2 therorys?

Alfred Wegener is best known for his theory of continental drift, which posits that continents were once part of a single supercontinent called Pangaea and have since drifted apart. He also proposed the concept of "polar wander," suggesting that the positions of the poles have changed over geological time, which contributed to the movement of continents. Wegener's ideas laid the groundwork for the modern theory of plate tectonics.
