When was the first paleomagnetic evidence for continental movement found?
Quick Answer
Strong paleomagnetic evidence emerged in the 1950s and 1960s.
The Full Story
Paleomagnetism became a major source of evidence for continental movement in the 1950s and 1960s. Scientists found that rocks preserve Earth’s magnetic field direction when they form, allowing them to track past positions of continents. Apparent polar wander paths and magnetic stripes on the seafloor strongly supported plate tectonics. This was one of the most convincing lines of evidence for moving plates.
