Magnetic Stripes Ocean Floor. Later after the planets magnetic field flips again the next stripe of new ocean floor aligns its polarity in. The surprising finding was that the ocean floor contained stripes of rock with different polarities.
During this time the earths magnetic field flips. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. A MODEL OF SEA-FLOOR SPREADING TEACHERS GUIDE ELLEN P.
Iron As sea floor spreading occurs what process causes the magnetic stripes on the ocean floor.
The striped magnetic pattern develops because as oceanic crust pulls apart magma rises to the surface at mid-ocean ridges and spills out to create new bands of ocean floor. What they discovered was that the magnetism of the ocean floor around mid-ocean ridges. At the mid-ocean ridge spreading axis these flips in the direction of the Earths magnetic field are recorded in the magnetization of the lava. Magnetic stripes and isotopic clocks Oceanographic exploration in the 1950s led to a much better understanding of the ocean floor.
