Final answer:
Landform features on once-connected continents exhibit similarities in geology, fossils, and paleoclimatic evidence due to being part of a supercontinent like Pangaea. Matching mountain ranges and similar fossil records across continents support this concept.
Step-by-step explanation:
Other landform features on continents that were once joined together, such as those that formed the ancient supercontinent Pangaea, would exhibit similarities in their geological formations, fossil records, and paleoclimatic evidence. Rock strata, mountain ranges, and coal deposits should have continuity across these joined continents. Also, similar fossilized plants and animals should be found across the now-separated continents.
By reconstructing the positions of continents using Wegener's evidence, when all landmasses were connected, there should be correspondences in the geological features like the Appalachian Mountains in North America lining up with the Caledonian Mountains in Northern Europe and Scotland. Additionally, fossils such as the Mesosaurus should be present in both South America and Africa, suggesting a prehistoric connection.
Finally, paleoclimate evidence, like glacial scratches pointing away from the South Pole on multiple continents, supports the idea of a unified land mass that has since drifted apart. This would also lead to related climatic patterns being evident across different continents that were once contiguous.
