What does the property of paleomagnetism state?

Paleomagnetism is the study of the Earth's magnetic field as recorded in rocks, sediments, and archeological materials. It states that magnetic minerals within these materials align with the Earth's magnetic field at the time of their formation, preserving a record of the field's direction and intensity. This property allows scientists to reconstruct past continental positions and movements, providing insights into plate tectonics and the geological history of the Earth.
