Through seafloor-spreading as iron rich minerals cool they become magnetized in the direction parallel to the existing magnetic field. As the magnetic fields change direction so will the magnetized minerals, allowing scientists to record each change in the seafloor as it spreads.

true
Strips of alternating magnetic polarities found in rocks in the ocean basins?
provide evidence for sea-floor spreading

rocks get older as you move away from ocean ridges
Strips of alternating magnetic polarities found in rocks in the ocean basins .?
provide evidence for sea-floor spreading
How do rocks along the central valley of the mid-ocean ridge provide evidence of the sea-floor spreading?
Magnetic field direction.
The magnetic particles in seafloor ridges are aligned differently in a repeating pattern How does this provide evidence for tectonic movement Why does it provide evidence?
Earth's magnetic field reverses over time; the changes show that seafloor has taken place over time.
