Alfred Wegener was a German scientist known for proposing the theory of continental drift in the early 20th century. This theory suggests that the Earth's continents were once joined together in a single landmass called Pangaea and have since drifted apart. It faced initial skepticism but later gained acceptance with the development of plate tectonics. Wegener's work revolutionized our understanding of Earth's geology and geography. Imagine continents as puzzle pieces slowly moving across the globe. His ideas paved the way for modern geology.
