The scientists divide into the sea using the Alvin, a miniature Sumerian, to collect rocks. The rocks were in the shape of pillows or thick like rope. So these rocks prove evidence for magma coming up in the ocean. Now evidence for magnetic stripes is that the earth behaves like a magnet sphere. The magnetic stripes of the sea also reverse themselves about all the time the stripes. Scientist started figuring this out when they tested the rocks. They are made up of bites of iron. That’s...
