* " . . . if new sea floor acquired the present magnetic field, spreading from a central ridge would produce magnetic stripes parallel to the ridge" ~ see related link below for additional information .

How would the history of reversals show itself on the ocean floor?
"Stripes" of alternating magnetic field in the basalt rock of the seafloor.
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
Does geomagnetic reversals represent a source of information on the rate of sea-floor spreading?
As mid ocean ridges create new seafloor over extended periods of time, the magnetic poles of the Earth reverse back and forth. The rocks on either side of a mid ocean ridge show the opposite magnetisms and appear striped. From knowing the approximate ages of these magnetic reversals, one can estimate the approximate age of each stripe.

The presence of magnetic domains of alternating orientation parallel to the plate boundaries.

What has cause the zebra pattern in the rock of ocean floor?
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.

What are pole reversals?
The direction of the Earth's magnetic field has reversed several times during its history. This causes the North magnetic pole to become a South magnetic pole and vice versa. We know this because of the direction of magnetism in the rocks on the ocean floor, which alternates in 'stripes' on either side of the mid-ocean ridges.
How would this history of reversals show itself of the ocean floor?
it tugs on the iron pieces in the sand causing ripples.

How a prediction and then evidence of magnetism in rocks on the ocean floor proved that the seafloor spreads?
The Earth's magnetic reversals have been recorded in newly forming oceanic seafloor basalt by the orientation of magnetic minerals which become frozen in place as the magma hardens. When the next reversal occurs, it as well becomes part of the ocean floor magnetic record.

What has casued the zebra pattern in the rock of the ocean floor?
The pattern only appears in images of magnetic field intensity, not really visible. Caused by changes in Earth's magnetic field over time especially reversals of the magnetic poles. "Stripes" represents different ages of rocks as they spread from mid-ocean ridges. Magnetic properties of lavas are set when they cool down and minerals such as magnetite crystallize.
