Mechanism of tectonic plates
WebFigure 4.3.2 Models for plate motion mechanisms (Steven Earle, “Physical Geology”). Some compelling arguments in favor of the ridge-push/slab-pull model are as follows: (a) plates that are attached to subducting slabs (e.g., Pacific, Australian, and Nazca Plates) move the fastest, and plates that are not (e.g., North American, South ... WebThe arrows show whether the plates are moving apart, moving together, or sliding past each other. Movement of the plates over Earth's surface is termed plate tectonics. Plates move at a rate of a few centimeters a year, about the same rate fingernails grow. How Plates Move Figure 3. Mantle convection drives plate tectonics.

The 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… WebThe mechanism by which tectonic plates move is still a subject of much debate among Earth scientists.
