The following tectonic plates currently exist on the Earth's surface with roughly definable boundaries.
Primary plates
These seven plates comprise the bulk of the seven continents and the Pacific Ocean.
Secondary plates
These smaller plates are generally shown on major plate maps, with the exception of the Arabian and Indian plates, because they do not comprise significant land area.
Tertiary plates
Tertiary plates are grouped with the major plate that they would otherwise be shown as part of on a major plate map. Mostly these are tiny microplates, although in the case of the Nubian-Somalian and Australian-Capricorn-Indian plates these are major plates that are rifting apart. Some models identify more minor plates within current orogens like the Apulian, Explorer, Gorda, and Philippine Mobile Belt plates. The remainder of the tertiary plates are the dwindling remains of much larger ancient plates. There may or may not be scientific consensus as to whether a tertiary plate is a separate plate yet, is still a separate plate, or should be considered a separate plate, thus new research could change this list.
§ African Plate
§ Antarctic Plate
§ Caribbean Plate
§ Cocos Plate
§ Eurasian Plate
§ Adriatic or Apulian Plate
§ Aegean Sea Plate (or Hellenic Plate)
§ Indo-Australian Plate
§ Juan de Fuca Plate
§ North American Plate
§ Pacific Plate
§ Philippine Sea Plate
§ South American Plate
