Plate tectonics and euler poles plate tectonic theory assumes a relatively cool rigid outer shell or lithosphere divided into a estimates of the thickness of continental lithosphere have come however from the analysis of the elastic rebound from unloading associated with the last.
Plate tectonics is a relatively new theory it was first proposed in 1912 by alfred lother wegener as a theory called continental drift wegener's theory was initially based upon the remarkable shape of our continents, particularly south america and africa.

The theory of plate tectonics states that the earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere process of one tectonic plate melting, sliding, or falling beneath another credits. Plate tectonics: theories analysis important evidence that supports the theory of plate tectonics comes from the studies of the magnetic properties and the ages of igneous rocks on the ocean floor all of these examples are very supportive of the plate tectonic theory.
