Additional information that was needed to prove Alfred Wegener's hypothesis of continental drift was plate tectonic theory - the mechanism behind the movement of the plates.
According to Alfred Wegener's hypothesis of continental drift, the earth was a giant piece of the merged continents called the "supercontinent or Pangea". Although he suggested that the continents are moving away from each other due to the rotation of the earth around its own axis, his idea was not accepted as it did not provide a sufficient explanation for the phenomenon of continental drift.
However, the theory of plate tectonics provides enough explanation as it suggests that the earth's outer layer is composed of plenty of rocks that move constantly to shape the land-scape of the earth.
In general, Alfred Wegener's hypothesis does not explain the mechanism behind the rotation of continents.
