Pangaea, the supercontinent, existed over 300 million years ago during the late Paleozoic and early Mesozoic eras. Its name, meaning "all lands" in Greek, aptly describes the conglomeration of today's continents into one vast landmass. Pangaea began to break apart around 200 million years ago due to the process of plate tectonics, eventually leading to the formation of the continents as we know them today. This ancient landmass played a crucial role in shaping Earth's geological and biological history, influencing the distribution of species and the development of ecosystems. The concept of Pangaea offers valuable insights into Earth's dynamic geological processes and its ever-changing landscape over geological time scales.
