The movement of large segments of the lithosphere over the surface of the Earth is known as the theory of?

Question

Answer 1

It's called Plate Tectonic theory.

he distinguishing characteristic of the lithosphere is not composition, but its flow properties. Under the influence of the low-intensity, long-term stresses that drive plate tectonic motions, the lithosphere responds essentially as a rigid shell and thus deforms primarily through brittle failure, whereas the asthenosphere (the layer of the mantle below the lithosphere) is heat-softened and accommodates strain through plastic deformation. Both the crust and upper mantle float on the more plastic asthenosphere. The crust is distinguished from the upper mantle by the change in chemical composition that takes place at the Moho discontinuity.

Answer 2

Plate Gin and Tonics... I mean, plate tectonics.

BTW, they plates don't move over the surface of the earth, they are the surface of the earth and they move over the mantle.

If this is a report, you might want to include the Giant Impact Hypothesis of moon formation. Part of that theory suggests that a lot of the lighter type of rock, Felsic, was ejected into space when a mars sized planet (Theia) collided with Earth. Continents tend to be made of the lighter Felsic rocks and the oceanic crust is the denser Mafic type of rock. Without the Giant Impact the Earth may have had too much Felsic rock on the surface making plate tectonics impossible. It's a hypothesis.
