Here's how paleoclimate data supports continental drift:
* Fossil Distribution: Fossils of similar land-based animals and plants were found on continents now separated by vast oceans. This suggests that these landmasses were once connected. For example, the discovery of fossils of the same species of reptile (Mesosaurus) in both South America and Africa, provided strong evidence of a past connection.
* Glacial Deposits: Traces of ancient glaciers were found on continents that are now far apart, but could be arranged to fit together like puzzle pieces. This supports the idea that these continents were once joined in a supercontinent (Pangea) and were later separated by continental drift.
* Rock Formations: Geologists discovered that the rock formations on different continents matched up, especially in areas where they could be theoretically joined together. This suggests that the rock formations formed on a single landmass before being split apart.
While "wetness" data itself isn't a direct piece of evidence, paleoclimate data, including information about past precipitation and climate patterns, can help support the idea of continental drift.
Key takeaway: Evidence from fossils, glacial deposits, and rock formations, all of which are influenced by climate, are crucial in understanding the movement of continents over geological time.
