What was wegeners theory of continatel drift?

Alfred Wegener's theory of continental drift, proposed in the early 20th century, suggested that continents were once joined together in a single landmass called Pangaea, which eventually broke apart and drifted to their current positions. He based his theory on evidence from fossil distributions, geological similarities across continents, and the fit of continental shapes. Although initially met with skepticism due to a lack of a mechanism for movement, Wegener's ideas laid the groundwork for the later development of plate tectonics, which provided the necessary explanation for the movement of continents.
