This diagram was similar to one Alfred Wegener drew to show the distribution of continents 300 million years ago. His theory of continental drift was met with skepticism in the scientific community.

Describe three forms of evidence Wegener used to support his ideas of continental drift.
Years later, the continental drift theory reemerged as plate tectonic theory, with two additional pieces of evidence.

Refer to the images above. Discuss in detail the two pieces of additional evidence that supported Wegener’s theory, now known as the theory of plate tectonics.
