Describe the Movement of Tectonic Plates
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries earthquakes are common and magma molten rock rises from the Earths mantle to the surface solidifying to create. Mechanisms Of Plate Movement Pbs Learningmedia In one to two sentences name and briefly describe the processes. . Additionally at destructive plate margins the denser oceanic plate sinks into the mantle under the influence of gravity which pulls the rest of the plate along with it. The inner core is 5500C - extremely hot. In places where convection currents rise up towards the crusts surface tectonic plates move away from each other in a process known as seafloor spreading Fig. 12 Do all tectonic plates move at the same speed. Plate tectonics is the unifying theory of geology. Plates at our planets surface move because of the intense heat in the Earths core that causes molten rock in the mantle layer to move. ...
