    How did the theory of plate tectonics change the world?The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes. In plate tectonics, Earth’s outermost layer, or lithosphere —made up of the crust and upper mantle—is broken into large rocky plates.

    What is the relative movement of tectonic plates?Earthquakes, volcanic activity, mountain -building, and oceanic trench formation occur along these plate boundaries (or faults). The relative movement of the plates typically ranges from zero to 100 mm annually. Tectonic plates are composed of the oceanic lithosphere and the thicker continental lithosphere, each topped by its own kind of crust.
