The rock's magnetic direction changes as the continent it is on moves due to plate tectonics. Rocks' magnetic direction will always align with Earth's current magnetic field.

The rock's magnetic direction was created when the rock was formed and aligned with the magnetic field of Earth at that time. As continents drifted, these rocks' magnetic direction may have become misaligned to Earth's magnetic field.

As new rocks are formed in ocean ridges, the magnetic direction will align with the direction the new rock is being pushed in.

The correct response is:
The rock's magnetic direction was created when the rock was formed and aligned with the magnetic field of Earth at that time. As continents drifted, these rocks' magnetic direction may have become misaligned to Earth's magnetic field.
This explains that the magnetic direction recorded in rocks is related to the Earth's magnetic field at the time of their formation. As tectonic plates move, the rocks can become misaligned with the current magnetic field.
