Evidence came from a technique called paleomagnetic dating: When lava cools and hardens, iron-rich minerals permanently point like frozen compass needles toward the Earth's magnetic poles.
Academic text (2004) -
Researchers analyzed rocks for paleomagnetic properties to understand tectonic plate movements.

Etymology
Paleomagnetic starts with paleo- meaning 'ancient' and ends with magnetic from magnet meaning 'related to a magnet'. So paleomagnetic is about the 'ancient magnetism' kept in rocks, which is why scientists use it to learn about Earth's past magnetic field and how continents moved.
