==Current plates== [[Geologist]]s generally agree that the following tectonic plates currently exist on [[Earth#Surface|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'').<ref name="Madaan 2020">{{cite web |last=Madaan |first=About Sonia |title=7 Major Tectonic Plates (Pacific, African, Eurasian, Antarctic and more) |website=Earth Eclipse |date=2020-08-18 |url=https://eartheclipse.com/geology/tectonic-plates.html#How_Many_Tectonic_Plates_Are_on_Earth |at=How Many Tectonic Plates Are on Earth?|access-date=2022-05-12}}</ref> ===Major plates=== [[Image:Tectonic plates boundaries World map Wt 180degE centered-en.svg|thumb|upright=1.85|Map showing Earth's principal tectonic plates and their boundaries in detail]] These plates comprise the bulk of the continents and the [[Pacific Ocean]].

For purposes of this list, a minor plate is any plate with an area less than {{convert|20|e6km2|abbr=unit}} but greater than {{convert|1|e6km2|abbr=unit}}. * {{annotated link|Amurian microplate}} * {{annotated link|Arabian plate}} – {{convert|5000000|km2|abbr=on}} * {{annotated link|Burma plate}} – {{convert|1100000|km2|abbr=on}} * {{annotated link|Caribbean plate}} – {{convert|3300000|km2|abbr=on}} * {{annotated link|Caroline plate}} – {{convert|1700000|km2|abbr=on}} * {{annotated link|Cocos plate}} – {{convert|2900000|km2|abbr=on}} * {{annotated link|Indian plate}} – {{convert|11900000|km2|abbr=on}} * {{annotated link|Nazca plate}} – {{convert|15600000|km2|abbr=on}}{{refn|group=note|15,600,000 km<sup>2</sup> is the original size before the 2017 split of the [[Coiba plate|Coiba]] and [[Malpelo plate|Malpelo]] plates.}} * {{annotated link|New Hebrides plate}} – {{convert|1100000|km2|abbr=on}} * {{annotated link|Okhotsk microplate}} * {{annotated link|Philippine Sea plate}} – {{convert|5500000|km2|abbr=on}} * {{annotated link|Scotia plate}} – {{convert|1600000|km2|abbr=on}} * {{annotated link|Somali plate}} – {{convert|16700000|km2|abbr=on}} * {{annotated link|Sunda plate}} * {{annotated link|Yangtze plate}} ===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 km<sup>2</sup>. Some models identify more minor plates within current [[orogeny|orogens]] (events that lead to a large structural deformation of [[Lithosphere#Earth's lithosphere|Earth's lithosphere]]) like the Apulian, Explorer, Gorda, and Philippine Mobile Belt plates.<ref>Bird, P.
