Using what you learned about plate tectonics, Alfred Wegener, and the basics of scientific investigation from the previous units discuss the following:
1. Did Wegener reveal his theory of continental drift too soon? For the sake of scientific investigation, how is revealing an explanation for a process early both risky and sometimes necessary?
2. Apart from lacking an explanation for how the continents could move across the surface of the Earth, Wegenerâ€™s research was met by skepticism for other reasons. How can a scientist overcome skepticism?What features of the scientific method can help prevent a scientist from being labeled a crackpot?
3. If Alfred Wegener were alive today, and had access to the technology and data we have now, share a form of evidence that he could have added to his theory or would have changed his theory. Try to share a different form of evidence from those shared by your classmates and/or add to their posts by describing how the evidence is collected, how the technology works to collect the data, or how this technology/evidence has been used in other applications.
