Aiden completed the 3-Dimensional Thinking where he created a data table for the age and distance of points on the Mid-Atlantic Ridge, he plotted the points on a graph, and he answered the follow-up question. He calculated the rate of seafloor spreading using R=D/T. He completed the 3-Dimensional Thinking where he analyzed a map of the location of tectonic plate boundaries and correlated them with the isochron map of the seafloor ages and the topographical map of the seafloor topography. He wrote an explanation for the correlation of the three maps. He wrote an explanation for how seafloor topography is evidence for plate tectonics.
