Plate tectonics (meaning plate structure) is a theory developed in the 1960's that earth's outer shell is divided into several plates that are in the lithosphere this theory explains how lithospheric plates move on earth's surface and the cause of earthquakes, volcanoes, oceanic trenches, mountain range formation, and other geologic phenomena. Tectonic plates, earthquakes, and volcanoes according to the theory of plate tectonics, earth is an active planet its surface is composed of many individual plates that move and interact, constantly changing and reshaping earth's outer layer.

Plate tectonics describes the large-scale motions of the earth's lithosphere it covers the concepts of continental drifting, which were developed during the. For decades, scientists have theorized that the movement of earth's tectonic plates is driven largely by negative buoyancy created as they cool new research, however, shows plate dynamics are driven significantly by the. The outer shell of the earth, the lithosphere, is broken up into tectonic plates the seven major plates are the african plate, antarctic plate.
