What is the process of the continental drift theory

Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

Idk if this is what youre looking for but I know that Alfred Wegener thought that all of Earth's continents were once part of an enormous, single landmass called Pangaea.
