The North American Plate is a tectonic plate covering most of North America, extending eastward to the Mid-Atlantic Ridge and westward to the Cherskiy Range in East Siberia. Image File history File links Download high resolution version (4150x2832, 3128 KB) The Earths tectonic plates. ... Image File history File links Download high resolution version (4150x2832, 3128 KB) The Earths tectonic plates. ... The tectonic plates of the world were mapped in the second half of the 20th century. ... World map showing North America A satellite composite image of North America. ... Courtesy USGS The ridge was central in the breakup of Pangaea The Mid-Atlantic Ridge is a mostly underwater mountain range of the Atlantic Ocean and Arctic Ocean that runs from 87°N (about 333 km South of the North Pole) to subantarctic Bouvet Island at 54°S. The highest... The Verkhoyansk Range (also Cherskiy Range) is a mountain chain of eastern Siberia, spanning ca. ... Siberian Federal District (dark red) and the broadest definition of Siberia (red) Udachnaya pipe Siberia (Russian: , Sibir; Tatar: ) is a vast region of Russia constituting almost all of Northern Asia. ...


The easterly side is a divergent boundary with the Eurasian Plate to the north and the African Plate to the south forming the northern part of the Mid-Atlantic Ridge. In plate tectonics, a divergent boundary (divergent fault boundary or divergent plate boundary), (but also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. ...  The Eurasian plate, shown in green The Eurasian Plate is a tectonic plate covering Eurasia (a landmass consisting of the continents Europe and Asia) except that it does not cover the Indian subcontinent, the Arabian subcontinent, and the area east of the Verkhoyansk Range in East Siberia. ...  The African plate, shown in pinkish-orange The African Plate is a tectonic plate covering the continent of Africa and extending westward to the Mid-Atlantic Ridge. ...


The southerly side is a boundary with the Cocos Plate to the west and the Caribbean Plate to the east.  The Cocos plate, shown in gray-blue, off the Pacific coast of Central America 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. ... Detail of tectonic plates from: Tectonic plates of the world. ...


The westerly side is a convergent boundary with the subducting Juan de Fuca Plate to the north and a transform boundary with the Pacific Plate to the south along the San Andreas Fault. 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. ... hi ... In plate tectonics, a transform boundary (also known as transform fault boundary, transform plate boundary, transform plate margin, slip boundary or conservative plate boundary) is said to occur when tectonic plates slide and grind against each other along a transform fault. ...  The Pacific plate, shown in pale yellow The Pacific Plate is an oceanic tectonic plate beneath the Pacific Ocean. ... View of the San Andreas Fault on the Carrizo Plain in central California, 35°07N, 119°39W The San Andreas Fault is a geological fault that runs a length of roughly 800 miles (1300 kilometres) through western and southern California in the United States. ...


On its western edge the Farallon Plate has been subducting under the North American Plate since the Jurassic period. The Farallon Plate has almost completely subducted beneath the western portion of the North American Plate leaving that part of the North American Plate in contact with the Pacific Plate and creating the San Andreas Fault. The Juan de Fuca, Cocos, and Nazca Plates are remnants of the Farallon Plate. The Farallon Plate is an ancient tectonic plate which began subducting as Pangaea broke apart during the Jurassic period. ... The Juan de Fuca plate sinks below the North America plate at the Cascadia subduction zone. ... The Jurassic Period is a major unit of the geologic timescale that extends from about 200 Ma (million years ago), at the end of the Triassic to 146 Ma, at the beginning of the Cretaceous. ... View of the San Andreas Fault on the Carrizo Plain in central California, 35°07N, 119°39W The San Andreas Fault is a geological fault that runs a length of roughly 800 miles (1300 kilometres) through western and southern California in the United States. ...


A remarkable feature of the North American Plate is that it is nowhere being subducted, yet it is measureably in motion, thus posing a problem for those who argue that subduction is the primary driving force for plate motion in plate tectonics.

Major Tectonic Plates of the World (245 words)
Three types of movement are recognized at the boundaries between plates: convergent, divergent and transform-fault.
Where an oceanic plate collides with a continental plate, the oceanic plate tips down and slides beneath the continental plate forming a deep ocean trench (long, narrow, deep basin.) An example of this type of movement, called subduction, occurs at the boundary between the oceanic Nazca Plate and the continental South American Plate.
Plate tectonics, the branch of science that deals with the process by which rigid plates are moved across hot molten material, has helped to explain much in global-scale geology including the formation of mountains, and the distribution of earthquakes and volcanoes.
