This is a list of tectonic plates on Earth's surface. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium). The composition of the two types of crust differs markedly, with mafic basaltic rocks dominating oceanic crust, while continental crust consists principally of lower-density felsic granitic rocks.

## Current plates

Geologists generally agree that the following tectonic plates currently exist on Earth's surface with roughly definable boundaries. Tectonic plates are sometimes subdivided into three fairly arbitrary categories: major (or primary) plates, minor (or secondary) plates, and microplates (or tertiary plates).[1]

### Major plates

These plates comprise the bulk of the continents and the Pacific Ocean. For purposes of this list, a major plate is any plate with an area greater than 20 million km2.

* Earth:African Plate - Tectonic plate underlying Africa – 61,300,000 km2
* Earth:Antarctic Plate - Major tectonic plate containing Antarctica and the surrounding ocean floor – 60,900,000 km2
* Earth:Eurasian Plate - Tectonic plate which includes most of the continent of Eurasia – 67,800,000 km2
* Earth:Indo-Australian Plate - A major tectonic plate formed by the fusion of the Indian and the Australian plates (sometimes considered to be two separate tectonic plates) – 58,900,000 km2
* Earth:Australian Plate - Major tectonic plate separated from Indo-Australian Plate about 3 million years ago – 47,000,000 km2
* Earth:Indian Plate - Minor plate that separated from Gondwana – 11,900,000 km2
* Earth:North American Plate - Large tectonic plate including most of North America, Greenland and part of Siberia – 75,900,000 km2
* Earth:Pacific Plate - Oceanic tectonic plate under the Pacific Ocean – 103,300,000 km2
* Earth:South American Plate - Major tectonic plate which includes most of South America and a large part of the south Atlantic – 43,600,000 km2

### Minor plates

These smaller plates are often not shown on major plate maps, as the majority of them do not comprise significant land area. For purposes of this list, a minor plate is any plate with an area less than 20 million km2 but greater than 1 million km2.

* Earth:Amurian Plate - A minor tectonic plate in eastern Asia
* Earth:Arabian Plate - Minor tectonic plate – 5,000,000 km2

* Earth:Sunda Plate - Tectonic plate including Southeast Asia
* Earth:Yangtze Plate - Small tectonic plate carrying the bulk of southern China

### Microplates

These plates are often grouped with an adjacent principal plate on a tectonic plate world map. For purposes of this list, a microplate is any plate with an area less than 1 million km2. Some models identify more minor plates within current orogens (events that lead to a large structural deformation of Earth's lithosphere) like the Apulian, Explorer, Gorda, and Philippine Mobile Belt plates. [2] One study has theorized that microplates may be the basic elements of which the crust is composed. [3]

## Ancient tectonic plates

In the history of Earth, many tectonic plates have come into existence and have over the intervening years either accreted onto other plates to form larger plates, rifted into smaller plates, or have been crushed by or subducted under other plates.

The following is a list of ancient cratons, microplates, plates, and terranes which no longer exist as separate plates. Cratons are the oldest and most stable parts of the continental lithosphere, and shields are exposed parts of them. Terranes are fragments of crustal material formed on one tectonic plate and accreted to crust lying on another plate, which may or may not have originated as independent microplates: a terrane may not contain the full thickness of the lithosphere.

### African Plate
