Question

1. according to the property of paleomagnetism, ____.

ocean rocks, regardless of when they are formed, have the same polarity
all rocks have a reversed polarity
iron - rich rocks show the location of the magnetic poles at the time of their formation
rocks do not possess magnetic properties

Explanation:

Paleomagnetism studies the magnetic fields preserved in rocks. Iron-rich rocks align with Earth's magnetic poles as they form, retaining a record of the poles' position at that time. The other options are incorrect: ocean rocks have varying polarity due to magnetic reversals, not all rocks have reversed polarity, and many rocks do have magnetic properties.

Answer:

iron-rich rocks show the location of the magnetic poles at the time of their formation
