The historical region of Pangaea is not a physical location that exists today; instead, it refers to a supercontinent that existed during the late Paleozoic and early Mesozoic eras. Pangaea is understood to have included almost all the landmasses of the Earth, which eventually separated due to the process of continental drift. The concept of Pangaea helps geologists understand the historical connections between modern continents and the evolution of Earth's landforms. While Pangaea itself cannot be visited, studying its formation and breakup provides insight into ancient environmental conditions and evolution.
