Explain why Wegner's use of shorelines to match continents in his reconstruction of Pangaea was criticized by other geoscientists and how that issue was subsequently resolved in Plate Tectonic Theory
What will be an ideal response?
Wegner used the shorelines to match continents but shorelines change constantly so they must have changed over time since the continents were together. Later scientists used the edge of the continental shelf to match continents in Plate Tectonic Theory because they have been submerged and are relatively unchanged since Pangaea broke apart.
