Description
The figure shows the varying directions the magnetic pole has taken based on basalt samples in Japan. The samples span over a time period that begins in the early Quaternary and ends in the Tertiary. Using the locations on the graph and their respective time periods, it can be seen that the Earth's magnetic pole has drifted and reversed over time.
