All of these pieces of evidence were used to support plate tectonics theory. Topographic profiles of the ocean floors showed the presence of mid-ocean ridges and deep-sea trenches, which were later explained by plate tectonics. Maps of rock magnetism helped identify patterns of seafloor spreading. Data classifying rocks by age also provided evidence for seafloor spreading, as the age of the rocks increased away from the mid-ocean ridges. Seafloor spreading was a key factor in the development of the theory of plate tectonics.
