The Origin of Continents by Alfred Wegener

"The Origin of Continents" by Alfred Wegener presents the idea that continents were once joined as a single landmass called Pangaea, which gradually broke apart and drifted to their current positions. Wegener gathered evidence from similar fossils, matching rock formations, and the shapes of coastlines that fit together like a puzzle. His theory, known as continental drift, challenged previous ideas by suggesting that Earth's surface is dynamic, with continents slowly moving over time. This work laid the foundation for modern plate tectonics, helping explain the Earth's geological evolution.
