Name one piece of evidence supporting the continental drift theory related to fossils.
Consider the animals or plants whose fossils are found across oceans.
Who proposed the theory of continental drift?
Think about the scientist who compiled the evidence for drifting continents.
True or False: The distribution of identical fossils on continents is evidence against continental drift.
Consider what identical species imply about land connectivity.
Analyze the differences between Wegener’s continental drift theory and the modern plate tectonics theory regarding their explanations for continental movement. What are the strengths and weaknesses?
Reflect on how theories have evolved from their inception.
Critique the evidence supporting continental drift. How does the jig-saw fit, similar rock ages, and fossil distribution complement or contrast each other?
Consider how each type of evidence interacts and builds upon the others.
