WebPlate Tectonic processes . Since the 1950s, several discoveries have led to a new understanding of how the Earth works. This includes Plate Tectonics, which explains the structure of the Earth's lithosphere (outer shell) and the forces that drive changes in its structure. Tectonics comes from the Greek word tekton, meaning builder. WebMar 31, 2024 · Plate movement is possible because the lithosphere-asthenosphere boundary is a zone of detachment. As the lithospheric plates move across Earth’s … new haven school foundation union cityThe outer layers of Earth are divided into the lithosphere and asthenosphere. The division is based on differences in mechanical properties and in the method for the transfer of heat. The lithosphere is cooler and more rigid, while the asthenosphere is hotter and flows more easily. In terms of heat transfer, the lithosphere loses heat by conduction, whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. This division should not be confus… intervision locations

WebWhen a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt.
