Plate Tectonics is a theory developed in the late 1960s, to explain how the outer layers of the Earth move and deform. The theory has caused a revolution in the way we think about the Earth.

Plate tectonics has proven to be so useful that it can predict geologic events and explain almost all aspects of what we see on the Earth.
