The plate tectonics theory is a theory that the earth outer shell is split into several plates that glides over the mantle and the rocky inner layer above the core.
The differences between continental drift and plate tectonic is it explains the structure and internal or workings of Earth. Continental drift goes with the theory that all continentals used to be Pangea.

The basic theory of plate tectonics is that along seafloor spreading zones, the continents are separating from one another. As they spread apart, magma comes to the surface and becomes new continental crust.
