Webb17 feb. 2024 · The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is divided into plates that move over the semi-liquid upper portion of the mantle, the asthenosphere. Thus, plate tectonics is a scientific theory that deals with the large-scale motion of the plates that makes up the Earth’s lithosphere. http://en.dzkx.org/article/doi/10.6038/cjg2024M0056
