The Cocos Plate (Chocos Plate) is an oceanic tectonic plate beneath the Pacific Ocean off the west coast of Central America, named for Cocos Island, which rides upon it.

The Cocos Plate is created by sea floor spreading along the East Pacific Rise, specifically in a complicated area geologists call the Cocos-Nazca spreading system. From the rise the plate is pushed eastward and pushed or dragged (perhaps both) under the less dense overriding Caribbean Plate, in the process called subduction. The subducted leading edge heats up and adds its water to the mantle above it. In the mantle layer called the asthenosphere, mantle rock melts to make magma. As a result, to the northeast of the subducting edge lies the continuous arc of volcanos stretching from Costa Rica to Guatemala and a belt of earthquakes that extends farther north, into Mexico. Seafloor spreading is a part of the theory of plate tectonics. ... The East Pacific Rise is a long north-south welt of sea floor spreading that roughly parallels the Pacific coast of South America. ...

The northeastern and eastern sides are convergent boundaries subducting under the North American Plate, the Caribbean Plate, and the South American Plate. The Cocos Plate is bounded by divergent boundaries to the south with the Nazca Plate and to the west with the Pacific Plate. Image File history File links Cocos-Caribbean. ... Image File history File links Cocos-Caribbean. ... In plate tectonics, a convergent boundary (convergent fault boundary, convergent plate boundary, or active margin) is where two tectonic plates slide towards each other and usually collide forming either a subduction zone with its associated island arc or an orogenic belt and associated mountain range. ...

The South American Plate is a continental tectonic plate covering the continent of South America and extending eastward to the Mid-Atlantic Ridge. ... The Nazca plate is shown in light blue on this map The Nazca Plate is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. ... The Pacific plate is shown in pale yellow on this map The Pacific Plate is an oceanic tectonic plate beneath the Pacific Ocean. ...


The Cocos and Nazca Plates are the remnants of the former Farallon Plate, which broke up about 23 million years ago. The boundary between the plates is marked by a hotspot under the Galapagos Islands. The Farallon Plate is an ancient tectonic plate which began subducting as Pangaea broke apart during the Jurassic period. ... In geology, a hotspot is a location on the Earths surface that has experienced active volcanism for a long period of time. ... NASA Satellite photo of the Galápagos archipelago. ...
