Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

Alfred Wegener was a geologist who studied landforms and gave his theory on continental drift. He also gave several related pieces of evidence of the drifting of continental blocks.

  • The continental drift theory was made on the group of the displacement of the tectonic plate due to the gravitational attraction of the moon and sun. He also highlighted the polewards wandering forces.
  • Wegener used landforms such as glacial valleys, the occurrence of coal, volcanism, and the similar nature of coastline as evidence to support his theory.  Presence of matching rocks, matching fossils of flor and fauna, and similar nature of landforms.
