WebbEarth’s lithosphere, or outermost shell, is broken up into large pieces called tectonic plates. These plates move slowly over the asthenosphere, a layer of softer rock below the … WebbPlate tectonics is the scientific theory explaining the movement of the earth’s crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth’s crust, and that the crust is broken into individual pieces called tectonic plates (Fig. 7.14). The movement of these tectonic ...

WebbThe plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the … WebbWhat is the slowest moving tectonic plate? The Arctic Ridge has the slowest rate (less than 2.5 cm/yr) and the East Pacific Rise near Easter Island in the South Pacific about 3 400 km west of Chile has the fastest rate (more than 15 cm/yr).

What Causes Tectonic Plates To Move? - WorldAtlas

WebbIt is a relatively slow movement, driven by thermal convection currents and other geological activity originating deep within the earth's mantle. This theory of plate tectonics replaced the previous one of continental drift, where it was thought that just the continents themselves drifted over the earth's surface.
