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 major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
Plate tectonics on Earth is hypothesized to be driven by “slab pull,” where the sinking of the more dense subducting plate provides the spreading force for mid-ocean ridges. [109] “Ridge push” is comparatively weak in Earth's plate tectonics. [109] Extensional features are abundant on icy moons, but compressional features are sparse. [109]
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
The tectonic plates of the lithosphere on Earth Earth cutaway from center to surface, the lithosphere comprising the crust and lithospheric mantle (detail not to scale). A lithosphere (from Ancient Greek λίθος (líthos) 'rocky' and σφαίρα (sphaíra) 'sphere') is the rigid, [1] outermost rocky shell of a terrestrial planet or natural satellite.

Geologists modeled the last billion years of Earth's tectonic plate evolution in unprecedented detail, then animated it in a mesmerizing video. Watch the last billion years of Earth's tectonic ...
The Indian plate (or India plate) is a minor tectonic plate straddling the equator in the Eastern Hemisphere. Originally a part of the ancient continent of Gondwana , the Indian plate broke away from the other fragments of Gondwana 100 million years ago and began moving north, carrying Insular India with it.

Tectonic plates are made up of Earth’s crust and the rigid top layer of the mantle, known as the lithospheric mantle. The planet has around a dozen large and irregularly shaped tectonic plates ...
