Theory of plate tectonics of the earth
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. WebbThe theory of plate tectonics describes the motions of the lithosphere, the comparatively rigid outer layer of the Earth that includes all the crust and part of the underlying mantle. The lithosphere is divided into a few dozen plates of various sizes and shapes, in general the plates are in motion with respect to one another.

WebbPlate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes. WebbPlate Tectonics, Seafloor Spreading, and Continental Drift Fig.1 Plate tectonics is a relatively new theory from the 1960’s that revolutionized the way geologists think about the Earth. According to plate tectonic theory, the outermost shell of the Earth is mobile, and broken into several large (and many smaller) tectonic plates that change size, shape and …

Webb11 jan. 2024 · The theory of plate tectonics is what brings together continental drift and seafloor spreading. Plates are made of lithosphere topped with oceanic and/or continental crust. The plates are moved around on Earth's surface by seafloor spreading. Convection in the mantle drives seafloor spreading.
