Our knowledge of the concepts surrounding the __(1)__ would not have surfaced were it not for the __(2)__ proposed by Alfred Wegener in the early 1900s. But despite the early pieces of evidence from his work, it wasn't until much later that the idea of moving continents could be validated by various features observed on the seafloor. Through extensive seafloor mapping, it was discovered that there are __(3)__ that run roughly parallel to continental coastlines.
