When was plate tectonics first accepted as the explanation for continental movement?
Quick Answer
It became widely accepted in the late 1960s.
The Full Story
The theory of plate tectonics was accepted by most geologists in the late 1960s after decades of debate. Earlier ideas like Alfred Wegener’s continental drift, proposed in 1912, lacked a convincing mechanism. Evidence from seafloor spreading, magnetic stripes on the ocean floor, and deep-sea earthquake patterns helped prove that Earth’s lithosphere is divided into moving plates. By about 1967, the modern theory had become the standard explanation.
