The relationship between Howard Foster's data about earthquake occurrences and Marie Tharp's data about mid-ocean ridges is that they both provide valuable information about the Earth's geology and tectonic activity. Foster's data on earthquake occurrences can help identify tectonic plate boundaries and areas of high seismic activity, which may correlate with the location of mid-ocean ridges identified by Tharp. By analyzing both sets of data together, scientists can gain a better understanding of the Earth's tectonic processes and the formation of mid-ocean ridges.
