What evidence proves pangaea exists?

Answer 1

Evidence #1: glaciers from the ice ages left striations in the substrate of southern South America, southern Africa, southern India, Antarctica, and southern Australia when they melted and these places are now extremely far apart and most of these continents found with the striations are not found in polar regions. Where the striations occur from the melted glaciers fits with the theory of continental drift and how Pangaea used to exist.

Evidence #2: other evidence Wegener had to support his theory of the existence of Pangaea was the distribution of climate belts. He studied sedimentary rock from different regions that were formed during the Paleozoic Era in order to determine a rough estimation of what latitude and longitude the present day continents were. He was able to determine that their were longitudinal climate belts during the Paleozoic Era where coal, desert, reefs, salt deposits, glaciers, and tropics aligned. Ex) He found that southern Europe and the southern part of North America used to be topical areas.

Evidence #3: the distribution of similar fossils around the world provides evidence for the previous existence of Pangaea. The only way to explain how fossils of the same animals being found on multiple continents today that existed during the Paleozoic and Mesozoic Era is through the once existing super continent. It is the only way to explain how so many fossils of land animals ended up on multiple continents.

Answer 2

Evidence supporting the existence of Pangaea includes the jigsaw-fit of the continents, similar rock formations across continents, matching fossils of ancient plants and animals found on different continents, and the distribution of certain species that can only be explained by a single landmass. Additionally, the movement of tectonic plates and mapping of seismic activity also support the concept of Pangaea.
