It helps them determine the frequency of shifts in the magnetic orientation of the Earth, and initially led to the confirmation of seafloor spreading at the mid-ocean ridges.
While studying the ocean floor, scientists found alternating bands of magnetism. Each band is magnetized with a polarity that is opposite the surrounding bands.
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
because they showed alternating bands of normal and reversed polarity.
The earths magnetic polarity at the time of rock formation.
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
Scientists date sea-floor rocks by looking at patterns in the rocks, including magnetic patterns, and by looking at the geomagnetic reversal time scale.
While studying the ocean floor, scientists found alternating bands of magnetism. Each band is magnetized with a polarity that is opposite the surrounding bands.
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
Through geomagnetic reversal whee they studying the magnetic properties of the seafloor.

molten material, magnetic stripes, and the ages of the rock.
What moves plate tectonics? Well, the magama underneath the plates move and shuffles.
Because of the stripes at the sea floor which are magnetic minerals
