heated by the decay of radioactive elements deep within the Earth. Although they only move a few inches per year, over hundreds of millions of years the continents are carried thousands of miles. Along their boundaries, the plates crumple, scrape, or pull apart from one another, giving rise...
The meaning of PLATE TECTONICS is a theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of thes

Earth’s lithosphere is composed of seven major tectonic plates, and additional minor plates. Each plate shifts somewhere between 0 and 10 mm annually. The boundaries where plates meet are sites of transformation. Depending on the type of boundary, the interactions of tectonic plates can cause ear...

For curved boundaries it is convenient to use intrinsic coordinates s and n, i.e., the arc length s and the coordinate n along the outward normal to the boundary (see Fig. 2.10). These are curvilinear coordinates and the derivatives on the boundary are expressed by the following relations ...
Most of the plate boundaries are activated obliquely with respect to the direction of far field stresses, as roughly only 8% of the plate boundaries total length shows a very low obliquity (ranging from 0 to 10掳, sub-orthogonal to the plate displacement). The obliquity along plate boundaries...
