The Antarctic Plate is a continental tectonic plate covering the continent of Antarctica and extending outward under the surrounding oceans. The Antarctic Plate has a boundary with the Nazca Plate, the South American Plate, the African Plate, the Indo-Australian Plate, the Scotia Plate and a divergent boundary with the Pacific Plate forming the Pacific-Antarctic Ridge.

Plate Tectonics, theory of global tectonics (geological structural deformations) that has served as a master key, in modern geology, for understanding the structure, history, and dynamics of the Earth’s lithosphere, which includes the crust.
Although the plate tectonics revolution in geological thought occurred only recently (in the 1960s and 1970s), the roots of the theory were established by earlier observation and deduction.
Where an oceanic tectonic plate is subducted beneath continental crust, the magma produced by subductive melting erupts from volcanoes situated among long, linear mountain chains, such as the Cordillera, up to 100 km inland from the zone of subduction.
The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which "float" on the fluid-like asthenosphere.
Tectonic plates are comprised of two types of lithosphere: continental and oceanic lithospheres; for example, the African Plate includes the continent and parts of the floor of the Atlantic and Indian Oceans.
Tectonic plates across the globe are constantly shifting - though slowly, usually by a few centimetres a year - with the magma beneath the crust.
