Bitesize tectonics
Tectonics (from Latin tectonicus; from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') are the processes that control the structure and properties of the Earth's crust and its evolution through time. These include the processes of mountain building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other. Tectonics also provide a framewo…

WebMar 22, 2024 · Slab pull is thought to be a more significant gravitational force acting on plates. In the current understanding of plate motion the movement is driven by the weight of cold, older, dense plate material sinking into the mantle at deep ocean trenches and pulling the rest of the plate slab with them as gravity causes them to slide downwards. Share : WebMar 27, 2024 · Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth's crust).
