Why Do Magnetic Stripes Appear on the Seafloor
The stripesrepresent the magnetic orientation of Earth at the time of theoceanic crusts. In the mid 1960s evidence of magnetic stripes on the seafloor convinced the geologic community of the validity of plate tectonics theory and it is often pointed to today as clinching evidence for the theory. Pin On Middle And High School Science Ideas Which of these. . Plate tectonics and reversals of the Earths magnetic field are responsible for the magnetic stripes found on the ocean floor. Why does the rock of the ocean floor have a pattern of magnetic stripes. As molten material cooled and hardenend the iron bits inside lined up in the direction of Earths magnetic poles creating a pattern of magnetized stripes. The rock of the ocean floor contains iron. Over hundreds of thousands of years the ocean floor spreads. The patterns reflect the creation and spreading of oceanic crust along the mid-oceanic ridges. During t...
