As the sea floor plates that are being created in the mid ocean ridges cool the magnetic orientation is recorded in the alignment of particles in the newly frozen rock. We can see alternating bands of polarity in the rock that show what the orientation was over geological time. The bands that spread outward from the ridges are separated by millions of years and provide a clear picture of sea floor spreading, and continental drift. |
