The theory developed in the 1960s that explained Wegener's idea of continental drift is the theory of plate tectonics. The theory proposes that the Earth's outer shell is divided into several plates that move and interact with each other at their boundaries, causing various geologic phenomena such as earthquakes, volcanic eruptions, and the creation of mountain ranges. The movement of these plates also explains the drifting of continents over time, as they are carried along by the motion of the plates on which they sit.
