Answer 1

Paleomagnetic evidence supports the theory of continental drift by showing that the magnetic minerals in ancient rocks align with the Earth's magnetic field at the time of their formation. As the continents move, these rocks retain a record of their original magnetic orientation, which can be determined through analysis. Studies of these magnetic alignments reveal that continents have shifted positions over millions of years, corroborating patterns of continental movement. This evidence, including magnetic signatures that differ from current positions, highlights how continents have drifted apart and affected the geological landscape.
