When was continental drift first proposed?
Quick Answer
Alfred Wegener first proposed it in 1912, and he expanded the idea in 1915.
The Full Story
Alfred Wegener introduced the idea that continents had once been joined together and later drifted apart. He first presented the concept in 1912 and developed it further in his 1915 book The Origin of Continents and Oceans. Wegener pointed to matching coastlines, fossils, and rock types on different continents as evidence. Although widely disputed at the time, continental drift became a key precursor to plate tectonics.
