Norman 2192 - FIRST EDITION, journal issue. Wegener was the originator and one of the chief defender's of the theory of continental drift. This, his first paper on the subject, attracted little attention, and it was only with the publication of a 2nd edition of his treatise in 1919 that his theory became a subject of wide controversy. It was largely ignored from the 1930s to the 1950s, when new paleo-magnetic evidence appeared to support the theory.
Wegener proposed the theory that the continents were once joined together in a single supercontinent he called Pangaea, and that they have since drifted apart over time. He collected and studied geological, paleontological, and climatological evidence from around the world to support his theory of continental drift, including matching geological formations, fossils, and rock types on different continents. Wegener proposed that the continents moved due to the gradual movement of the Earth's crust, driven by convection currents in the mantle. His theory of continental drift inspired further research and discoveries, including the development of plate tectonics theory in the 1960s and 1970s, which provided a mechanism for the movement of the Earth's crust.
Overall, Wegener's contributions and achievements in the development of the theory of continental drift laid the foundation for our modern understanding of the structure and movement of the Earth's crust. Although his theory was initially met with skepticism and criticism, it has since been widely accepted and has had a significant impact on the field of geology. - Visit our website to see more images!
