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)
The North American plate is a tectonic plate containing most of North America, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores.With an area of 76 million km 2 (29 million sq mi), it is the Earth's second largest tectonic plate, behind the Pacific plate (which borders the plate to the west).
The Pacific plate (carrying the city of Los Angeles) is moving northwards with respect to the North American plate. The Queen Charlotte Fault on the Pacific Northwest coast of North America The Motagua Fault , which crosses through Guatemala , is a transform boundary between the southern edge of the North American plate and the northern edge of ...
The regions that are not geographically North American but reside on the North American Plate include parts of Siberia (see the Geology of Russia), [2] and Iceland, and Bermuda. A discussion of North American geology can also include other continental plates including the Cocos Plats and Juan de Fuca Plate being subducted beneath western North ...
As the edge of North America moved away from the hot rift zone, it began to cool and subside beneath the new Atlantic Ocean. This once-active divergent plate boundary became the passive, trailing edge of westward moving North America. In plate tectonic terms, the Atlantic Plain is known as a classic example of a passive continental margin. [20]
Territorial evolution of North America of non-native nation states from 1750 to 2008. The 1763 Treaty of Paris ended the major war known by Americans as the French and Indian War and by Canadians as the Seven Years' War / Guerre de Sept Ans, or by French-Canadians, La Guerre de la Conquête.
Where the plates meet, their relative motion determines the type of plate boundary (or fault): convergent, divergent, or transform. The relative movement of the plates typically ranges from zero to 10 cm annually. [5] Faults tend to be geologically active, experiencing earthquakes, volcanic activity, mountain-building, and oceanic trench formation.
