The theory of continental movement is called what?

Hello, i stated the basic information about Continental Drift below...hope this helps you .

So lets start off with Continental drift, Continental Drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics.  The theory of continental drift is most associated with the scientist Alfred Wegener. In the 20th century's, Wegener published a paper explaining in detail his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift. Pangaea a landmass long ago when dinosaurs roamed the planet, was all of the countries today all placed in one whole landmass,  Wegener was convinced that all of Earth’s continents were once part of an enormous, single landmass called Pangaea. Therefore stating his theory of continental drift.

I have tried to explain simply the basic information to know about this topic , hope it helps you out. Let me know if you need any further information or detail of this topic. I also posted a picture to show you an example of the one, whole, huge landmass called Pangaea.
