During the development of continental drift theory, there was not much exploration of the oceanic part of the world, only continental. Once people began to pay attention to the ocean, geologists found that the floor was spreading, and in different rates at different spots.[1] There are three different main ways in which plates can move: transform, divergent, and Convergent.[9] As well, there can be Rifts, areas where the land is beginning to spread apart.[10]
