Magnetic Stripes On The Ocean Floor. They showed alternating bands of normal and reversed polarity. These patterns of stripes provide the history of seafloor spreading.
Magnetic Stripes Molten rock erupts along a mid-ocean ridge then cools and freezes to become solid rock. Magnetic stripes and isotopic clocks Oceanographic exploration in the 1950s led to a much better understanding of the ocean floor. Rock formations magnetic seafloor stripes age of rocks.
The public has not heard anything new about this pivotal find.
Iron As sea floor spreading occurs what process causes the magnetic stripes on the ocean floor. The direction of the magnetic field of the Earth at the time the rock cools is frozen in place. Over time the Earths magnetic field reverses its north-to-south polarity and the magnetic minerals point in the. Last time I mentioned that measuring magnetic stripes on the ocean floor indicated the Earths magnetic field periodically flips.
