Understanding that Earth's continents were once connected into a single landmass helps explain why the term Pangea is used. Pangea, meaning “all Earth” in Greek, represents the ancient supercontinent that existed roughly 335 to 175 million years ago before the landmasses split apart due to plate tectonics. The idea is supported by fitting coastlines, matching fossil records, and similar rock formations across now-distant regions, all pointing to a unified origin. The other options point to current geographic areas or country pairings and do not describe a single historical landmass, so they don’t capture this idea of an ancient, shared continent.
