The video explores Earth's continents, focusing on the fit between South America and Africa, which intrigued scientists and led to Alfred Wegener's theory of continental drift. Wegener proposed that continents were once part of a super-continent called Pangaea. He supported his theory with fossil, climate, and geologic evidence, although he couldn't explain the mechanism behind the drift.

What does the presence of similar fossils on different continents suggest?

What problem did Wegener face regarding his theory of continental drift?
