Sea-floor spreading

Magnetic reversal proves seafloor spreading because we can see the polarity of the Earth’s magnetic field in rocks. As magma cools, particles in it solidify in the direction of the magnetic field. By looking at these particles, scientists can see the polarity of the magnetic field at the time the rocks were created.
