WebPlate tectonics is a relatively new theory in the field of geology. It states that the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the athenosphere, which lies over the mantle. Much of the earth's seismic activities occurs at the boundaries of these plates. WebCurrent plate movement can be tracked directly by means of ground-based or space-based geodetic measurements; geodesy is the science of the size and shape of the Earth. … reader rabbit cd
