[Mark A Richards; Richard G Gordon; Robert D Van der Hilst;] -- Here is the state-of-the-art on the dynamics of plate motions, and the questions about it that remain. Earth scientists and students will find it a rich resource for new interpretations and research. The new global tectonics that emerged three decades ago profoundly changed our view of the Earth and its evolution. Although the theory of plate tectonics gives a kinematic description of much of Earth's surface motions, our dynamical understanding remains incomplete and unsatisfactory in many ways. Key remaining issues include the mechanics of plate boundaries and intraplate deformation, the Cited by: important challenge to integrate plate tectonics into mantle dynamics in order to allow a full dynamic treatment of Earth motion and deformation on all scales. Much progress has been made in understanding the dynamics of mantle con-vection, plate tectonics, and plumes, but a fully integrated model incorporating both plate motions and mantle dynam-.   absolute plate motions in a global plate model, including the reconstruction of the global network of dynamics of plate tectonics and mantle and on the flooding history of .

  Delineating the driving forces behind plate motions is important for understanding the processes that have shaped Earth throughout its history. However, the accurate prediction of plate motions, boundary-zone deformation, rigidity, and stresses remains a difficult frontier in numerical modeling. We present a global dynamic model that produces a good fit to such parameters by .   Fig. 1 shows a map of the velocity field of global plate motion, and Tab. 1 gives a list of the rotation rates-Ω of the major plates,.We can see that the plate movements are not homogeneous. The horizontal velocities and values of the Philippine Sea (PHIL), the Pacific (PCFC), the Cocos (COCS), the Nazca (NAZC), the Australia (AUST), the Indian (INDI) and the Arabian (ARAB) plates are.   Multiple models of absolute plate motion have been proposed for the Cretaceous-Tertiary period, however, estimating the robustness and limitations of each model remains a significant limitation for refining both regional and global models of plate motion as well as fully integrated and time dependent geodynamic models.

Article history: Received 11 December face plate motions with the dynamics of the underlying mantle (Torsvik et al., ). Observations from linear seamount chains Global analyses of plate motions relative to hotspots are com-plicated by the difficulty in constructing a well-constrained RPM.   Global crust is composed of tectonic plates, which are constantly in motion above mantle. The majority of global plate can be characterized by long term, short term and instant movements. Long term motion, basically defined as the background field, represents the fundamental features of crustal movement in the past several millions of years [1]. A plate tectonic "traffic jam" in one part of the world, like a subduction zone that becomes the site of a continent-continent collision, could change the dynamics of plate motion all over the planet.
