In the early 1900s, a major debate emerged when German geophysicist and meteorologist Alfred Wegener proposed his continental drift theory. He noticed that Earth’s major landmasses could be itted together like a jigsaw puzzle and stated that the continents had once been joined together in a single landmass, Pangaea, and that they had later drifted apart. He could not provide a mechanism so his work was derided and ignored for decades until they provided proof of sealoor spreading that resulted in the plate tectonics theory. Even though Wegener had a limited amount of data or available technology compared to the present time, his theory was not changed dramatically.
