On the broadest level, they tend to follow the “supercontinent cycle” — continents combine together to form one giant supercontinent, then break again into separate continents, then the process repeats again. A full cycle occurs about once every 300-500 million years. The last supercontinent was Pangaea, which existed about 200 million years ago, and before that, Rodinia, which existed about 700 million years ago. Some of the most famous continental configurations that no longer exist today are Pangaea (which contained the world’s entire land mass except for a small part of present-day China), Gondwana (South America, Africa, Australia, and Antarctica all merged together), Laurasia (North America and Eurasia together), Baltica (a small subcontinent made up of the present-day Baltic states), India (once an independent subcontinent), and the Kerguelen conti
