• Magnetometers in the oceans discovered strange patterns.
  • This pattern of stripes is like what they discovered on the seafloor.
  • There are stripes with different magnetism.
  • Some stripes have normal polarity and some have reversed polarity.
  • These stripes surround the mid-ocean ridges.
  • Scientists found that magnetic polarity was normal at mid-Ocean ridge but reversed in symmetrical patterns away from the ridge center.
  • This leads to an important idea: some process is creating seafLoor at the ridge crest.
  • Somehow the older seafl floor is being destroyed.
