Suppose a magnetic reversal occurred today. How would new rocks at mid-ocean ridges differ from rocks that formed last year?

They would have the magnetic parts of the rocks oriented differently. This leaves a trace that allow scientists to find out how often this actually happens (as far as I remember, it's on average once in 800 000 years)

If a magnetic reversal occurred today, new rocks at mid-ocean ridges would be magnetized with the new magnetic orientation, in contrast to rocks formed last year which would remain align with the current magnetic field. This concept of paleomagnetism allows scientists to study past magnetic field behaviors and geological events. The difference in magnetic orientation between new rocks and older rocks would provide crucial information about the timing of magnetic reversals.
