Who Discovered Plate Tectonics?

Answer

Plate tectonic theory began in 1915 when Alfred Wegener proposed his theory of 'continental drift'. Wegener proposed that the continents moved through crust of ocean basins, which made them look like they fit together like a puzzle. Wegener was not the first to notice this puzzle-like fit of the continents (Magellan and other early explorers noticed this on their maps), but he ws the first to realize that continents separated now may once have been joined.
