What is the theory of continental drift and what evidence supports it?
Understand the Problem
The question appears to be focused on the concept of continental drift, highlighting historical theories and evidence supporting the idea, such as the matching of coastlines and fossil distribution. It's likely seeking a summary or explanation regarding these topics.
Answer
The theory of continental drift is supported by the fit of continents, fossil distributions, matching geological formations, and past climatic evidence.
The theory of continental drift, proposed by Alfred Wegener, suggests that the continents were once a single landmass called Pangaea and have since drifted apart over time. Key evidence supporting this theory includes the jigsaw-like fit of continents, distribution of fossils, matching geological formations across continents, and evidence of past climates.

More Information
Alfred Wegener's theory of continental drift was initially controversial but gained acceptance as more evidence, such as seafloor spreading, supported the idea that continents move.
Tips
A common mistake is to confuse the theory of continental drift with plate tectonics. Continental drift is the hypothesis that continents move, while plate tectonics describes the mechanism behind this movement.
