Plate tectonics

Plate tectonics is a theory of geology developed to explain the phenomenon of continental drift and is currently the theory accepted by the vast majority of scientists working in this area.

In the theory of plate tectonics the outermost part of the Earth's interior is made up of two layers: the outer lithosphere and the inner asthenosphere.

The lithosphere essentially "floats" on the asthenosphere and is broken-up into ten major plates: African, Antarctic, Australian, Eurasian, North American, South American, Pacific, Cocos, Nazca, and the Indian plates.
