The theory of plate tectonics makes the occurrence of Pangaea possible. It suggests that the Earth's lithosphere is divided into several large plates that move and interact with each other over time. In the case of Pangaea, these plates came together to form a supercontinent before breaking apart again.
The theory of continental drift.

It is supported by data.
One is based on scientific data the other is based on the unproven.

No. It's never correct to say that anything is "only" a theory or "just" a theory or"merely" a theory or "nothing but" a theory or an "unproven" theory.A theory can never be proven, but it can be dis-proven in two seconds. If a theoryhas been around for three hundred years and it hasn't been dis-proven yet, thenthat's a pretty good indication that you can trust the statement it makes.
What the heck?? That makes no sense.
