When was the theory of plate tectonics first widely accepted?
Quick Answer
It became widely accepted in the late 1960s, especially after 1967–1968.
The Full Story
The theory of plate tectonics emerged from several earlier ideas, including continental drift and seafloor spreading. By the late 1960s, evidence from ocean-floor magnetic stripes, earthquakes, and global mapping showed that Earth’s lithosphere is broken into moving plates. In 1967 and 1968, landmark papers by researchers such as Jason Morgan, Dan McKenzie, and Xavier Le Pichon helped formalize the theory. It quickly became the unifying framework for explaining earthquakes, volcanoes, mountain building, and ocean basins.
