WebPlate tectonics is an idea that explains how slow motions within the mantle of Earth move large segments of the crust, resulting in a gradual “drifting” of the continents as well as the formation of mountains and other large-scale geological features. WebJan 1, 2015 · • Plates with a large area of continent move slowly (e.g., Eurasia) because they have a deep continental keel connected to the mantle. o For this reason continental plates more likely to be...

WebFeb 11, 2024 · Evidence of Plate Motions. Earth’s outer shell is broken into tectonic plates that move relative to one another. The plates rip apart at divergent plate boundaries, crash together at convergent plate boundaries, and slide past each other at transform plate boundaries. Modified from “Beauty from the Beast: Plate Tectonics and the Landscapes ... Web10.5 Mechanisms for Plate Motion. It has been often repeated in this text and elsewhere that convection of the mantle is critical to plate tectonics, and while this is almost certainly so, there is still some debate about the … WebPlate Tectonic Resistiveforces (fig.5) are exerted on the overriding plate in a subduction zone at the contact with the descending slab. This force is thought to result in a shear stress that is distributed over the subduction thrust interface, that dips in the direction of the plate's stg business
