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.

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 appears clear that heat within the Earth is the ultimate driving … WebHelp students understand how plates move in this plate tectonics activity. Your students will be engaged as as they observe convection currents in action. Students will apply their observations to the convection currents in Earth's Mantle and how the convection moves the tectonic plates. putbucketcors
