The theory is called plate tectonics.
The place where tectonic plates touch
a theory called Earth Crust Displacement (ECD)
the theory of plate tectonics
Continental drift is the theory that "plates" on the Earth are constantly in motion and have been for millions of years. Tectonic plates are the actual moving plates.
The theory that implies that large portions of the earth's crust move is called the Theory of Tectonic Plates. According to this theory, the earth's crust is split up into portions called tectonic plates and they move. When tectonic plates rub against each other, earthquakes occur.

The Continental Drift theory.
The theory of plate tectonics says that the Earth's lithosphere is divided into "plates" that are determined by overall movement.The theory combines ideas on seafloor spreading and continental drift
every year the plates move slowly and when the plates meet, that's what causes an earth quake
The theory of plate tectonics helps to explain how earthquakes and volcanic eruptions occur.
