Convection tectonics

WebPlate tectonics refers to the movement of the rigid plates around the surface of Earth. The outer portion of the planet, or lithosphere, is relatively rigid because it is relatively cold. The lithosphere varies in thickness but is typically a hundred or so kilometers thick. 1. convection drag - the idea that when magma moves to the surface, where the … WebFigure 5 shows Earth’s major tectonic plates. Convection causes these plates to move about Earth’s surface. Tectonic plates move quite slowly: about as fast as your fingernails grow (up to ~10 cm per year). The Theory of Plate Tectonics explains the causes and nature of plate motions and interactions.

Earth's scientists are still debating amongst …

WebThis convection is a driving force for the movement of tectonic plates, as the horizontal movements of mantle under the crust drag the plates with them. At places where convection currents in the mantle are moving upward, new lithosphere forms and the plates move apart (diverge). WebMantle convection could be the primary cause of plate tectonics. Alternatively, mantle convection could be a more passive response to plate motions. In either case, it …
