Paleomagnetic evidence supports the theory of continental drift by revealing the historical magnetic orientation of rocks formed at various times in the Earth's history. When volcanic rocks solidify, magnetic minerals align themselves with the Earth's magnetic field, preserving a record of that direction. Studies of these orientations show that rocks of the same age from different continents have different magnetic signatures, indicating they were formed at different latitudes. For instance, rocks that now lie near the equator may show evidence of having formed closer to the poles, suggesting that the continents have moved over time. This provides compelling evidence for the dynamic nature of the Earth's lithosphere and the movement of tectonic plates, supporting the broader theory of plate tectonics.
