     The Antarctic plate, shown in blue

The Antarctic Plate is a 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.

The Antarctic plate is roughly 60,900,000 square kilometers[1]. It is the fifth biggest plate in the world.

The Antarctic plate movement is estimated at least 1 centimeter/per year towards the Atlantic Ocean.
