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).
North American plate – Large tectonic plate including most of North America, Greenland and part of Siberia – 75,900,000 km 2 (29,300,000 sq mi) Pacific plate – Oceanic tectonic plate under the Pacific Ocean – 103,300,000 km 2 (39,900,000 sq mi)
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 ...
The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2,000 km (1,200 mi) long geological rift in the center of the North American continent and south-central part of the North American plate. It formed when the continent's core, the North American craton , began to split apart during the Mesoproterozoic era of the Precambrian , about 1.1 ...
The Pacific Plate forced its way under the North American plate, triggering geologic upheaval, including volcanism, on the west coast. [62] Ichthyosaurs remained the dominant marine reptiles of the Early Jurassic, but as the Jurassic progressed that title was gradually transferred to the plesiosaurs.
The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession of caldera-forming eruptions.
The vast majority of North America is located on the North American Plate, centered on the Laurentia craton. Parts of California and western Mexico form the partial edge of the Pacific Plate; the two plates meet along the San Andreas Fault.
