If a continent twists as it moves over time (see Figure 3.21 for example), would magnetic particles locked in rocks still point north (or south)?

To determine

Whether the magnetic particles locked within the rocks of a continent still point north if the continent twists as it moves over time.

Explanation of Solution

The orientation and alignment of the particles in a continent may not alter due to the movement of the continent, since these particles remain “frozen” within the rock and are unable to rotate. However, the case may be different if the rock itself is being rotated by geological forces during the movement of the continent...
