Flexi Says: Alfred Wegener is generally credited as the first scientist to propose the idea of continental drifting which is a direct result of plate tectonics. But very few scientists accepted his idea. He needed a mechanism that they would accept. The continental drift hypothesis was put to rest for a few decades. It was when technology could provide even more evidence for continental drift that scientists looked into the idea again. Using technology, scientists would find more evidence that continents had drifted and learned about the mechanism. This led to the theory of plate tectonics.
