Today, the Earth’s seven continents are distributed across the surface, with North and South America occupying one hemisphere; Africa, Europe, Asia, and Australia occupying the other; and Antarctica sitting alone around the South Pole. However, these continents were arranged in entirely different configurations throughout Earth’s history. On occasion, they formed supercontinents like Gondwana (circa 550 to 180 million) and Pangaea (circa 335 to 200 million years ago) that were surrounded by “superoceans.”
