Alfred Wegener (continental drift theory)

Alfred Wegener was a scientist who proposed the theory of continental drift, suggesting that continents were once joined together as a single landmass called Pangaea. Over millions of years, this supercontinent broke apart, and the land masses drifted to their current positions. His idea was based on evidence like the matching coastlines of continents, similar fossils found across oceans, and geological formations. While initially controversial, later scientific discoveries confirmed that Earth's continents are indeed slowly moving due to tectonic plate activity deep beneath the Earth's surface.
