The correct answer is: **distinct bands in rocks that contain magnetic particles**.
This phenomenon is known as magnetic striping, which occurs due to the periodic reversal of Earth's magnetic poles and is recorded in the rocks that form at mid-ocean ridges. As new magma rises and cools, iron-rich minerals align with the current magnetic field, creating distinct bands that show the history of magnetic reversals.
