Answer 1

The correct response is:

distinct bands in rocks that contain magnetic particles

This phenomenon is known as magnetic striping and is a result of the periodic reversal of Earth's magnetic poles during the formation of new oceanic crust at mid-ocean ridges. As magma rises and solidifies, iron-rich minerals align with the current magnetic field, creating distinct bands that record the history of magnetic reversals.
