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, Wegener’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.
