Magnetic Reversal Data and Timescale
The figure represents magnetic data taken from multiple locations around the world. It shows whether or not the samples were formed during a time that had a normal or reversed magnetic field. Each dot represents a different rock sample, which were then used to determine when the magnetic fiel ...

Magnetic Rock Polarity Data Table
The table contains data for magnetic polarities of 6 rock samples taken in New Mexico. These rocks act as a storage device for magnetic field data because they can record the strength and direction of the magnetic field at the time of their formation. They are able to record the magneti ...
