In 3-5 sentences, describe how paleomagnetic evidence supports the theory that continues change position (drift) over time.

Explanation:

The earth magnetic field changes direction and its strength varies from year to year. This results in magnetic anomalies within a rock body as magnetic elements and minerals records the changing direction of the magnetic field.

As new magma is brought near the mid-oceanic ridge, the older ones are pushed backwards and they show a different magnetic field direction from the cooling magma. This is usually evident in the orientation of the magnetic minerals.
