- 5. Multiple ChoiceHow does fossil evidence support Wegener's hypothesis of continental drift?Similar fossils are found along continental margins that appear to join together.Fossils are found in areas where the present-day climate could not have supported the organisms that made the fossils.Similar fossils of giant, land-dwelling dinosaurs are found on continents separated by oceans.all of the above
