In digging on it, Ancient Supercontinents and the Paleogeography of Earth looks to be an interesting book https://www.sciencedirect.com/book/9780128185339/ancient-supercontinents-and-the-paleogeography-of-earth https://www.sciencedirect.com/book/9780128185339/ancient-sup... This appears to be part of a geologic scale cycle - https://www.livescience.com/38218-facts-about-pangaea.html https://www.livescience.com/38218-facts-about-pangaea.html > The current configuration of continents is unlikely to be the last. Supercontinents have formed several times in Earth's history, only to be split off into new continents. Right now for instance, Australia is inching toward Asia, and the eastern portion of Africa is slowly peeling off from the rest of the continent. > Based on the emergence of other supercontinents in the Precambrian supereon (4.5 billion to 541 million years ago), it appears that supercontinents occur periodically every 750 million years, according to a 2012 study in the journal Gondwana Research (opens in new tab). > Most scientists believe that the supercontinent cycle is largely driven by circulation dynamics in the mantle, according to a 2010 article in the Journal of Geodynamics (opens in new tab). Water/land hemispheres would then be an artifact of that cycle. Given that cycle, it will happen again - https://www.sciencealert.com/scientists-think-earth-s-next-supercontinent-might-look-like-one-of-these https://www.sciencealert.com/scientists-think-earth-s-next-s...
