WebIt's what the lithospheric plates-- when we talk about plate tectonics-- are riding on top of. It's kind of the gummy material that allows it to actually move, that allows the rigid layer to actually move on top. So it starts below the lithosphere, and it ends at around 660 kilometers deep. So this right here is 660 kilometers deep. WebIn this model, plates move through a combination of pull from the weight of the subducting edge of the plates, and through the outward pushing of an ocean ridge where magma is rising and forming new crust (Figure 4.3.2). Figure 4.3.2 Models for plate motion mechanisms (Steven Earle, “Physical Geology”). Some compelling arguments in favor of ...
