The correct response is:
distinct bands in rocks that contain magnetic particles
This phenomenon is known as magnetic striping, which occurs when molten rock cools at mid-ocean ridges and the magnetic minerals within align according to the Earth's magnetic field. Over time, as the magnetic poles reverse, distinct bands of normal and reversed magnetic polarity can be found in the rocks, providing a geological record of these reversals.
