how do magnetic stripes on the ocean floor support the idea of sea floor spreading |
parrellel magnetic stripes with similar chemical composition,age, and magnetic characteristics that exist on either side of the mid ocean ridge. The pairs of similar magnetic stripes confirm that the oceanic crust is formed at mid ocean ridges.It is carried away from the center this is the process of seafloor sspreading. |
