When was the theory of plate tectonics widely accepted?
Earth scienceGeology
Quick Answer
By the late 1960s, with the 1967–1968 synthesis of seafloor spreading, subduction, and global fault patterns.
The Full Story
Plate tectonics was not accepted overnight; it emerged from several lines of evidence during the 1960s. In 1967–1968, researchers such as W. Jason Morgan, Dan McKenzie, and Xavier Le Pichon helped formalize the idea that Earth’s lithosphere is broken into moving plates. Earlier clues came from seafloor spreading, magnetic stripes on the ocean floor, and matching earthquake belts and mountain chains. By the early 1970s, plate tectonics had become the central framework of modern geology.
