WebbPlate Tectonics By the 1970s geologists had agreed to use the term “plate tectonics” for what has become the core paradigm of their discipline. They used the term “plates” because they had found evidence that not just continents move, but so do whole plates of the Earth’s crust. Webb2 okt. 2024 · “Plate tectonics really comes from the oceans. It was when we discovered the oceanic ridges, subduction zones and transform faults, and so forth,” said John Dewey from Oxford University,...

WebbIn 1965, a Canadian geophysicist, J. Tuzo Wilson, combined the continental drift and seafloor spreading hypotheses to propose the theory of plate tectonics. Tuzo said that Earth’s crust, or lithosphere, was divided into large, rigid pieces called plates. These plates “float” atop an underlying rock layer called the asthenosphere.
