How is plate tectonic theory different from continental drift theory?

They are actually part of the "same" theory. Seafloor spreading and subduction are the driving forces of continental drift. Pangaea was the Earth's only continent 4 billion years ago. Tectonic plates are small plates, while continent drift is several tectonic plates moving as a mass (continent). There are 21 large plates and dozens of smaller ones.
