What Is the Theory of Plate Tectonics?

Answer

The theory of plate tectonics refers to the science that suggests that the outer rigid layer of the earth is divided into plates that move relative to each other across the surface of the earth. It encompasses the study of plates, plate boundaries and the effects of the movement of these plates. Plate movement is often too slow to be measured.

Ask.com Answer for: what is the theory of plate tectonics
The theory of plate tectonics holds that the Earth's crust is composed of mobile plates, which have moved throughout Earth's history. This movement is caused by thermal convection currents produced by the Earth's mantle.
The theory of plate tectonics states that the upper layer of the Earth ( known as the lithosphere) is divided into plates, or tabular blocks, that interact with each other over time. The crust and part of the solid upper mantle comprise each crustal plate. The true mechanism for the movement of the crustal plates is still unknown.
