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).
This rift marks the actual boundary between adjacent tectonic plates, where magma from the mantle reaches the seafloor, erupting as lava and producing new crustal material for the plates. Before 2002 Explorer Ridge was the least explored of the northeast Pacific spreading centers, even though it was known to have robust hydrothermal activity ...
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 ...
To the northwest of the triple junction the Pacific plate currently has 15 degrees of oblique convergence, passing under the North American plate along the Queen Charlotte transform fault zone. [3] The Explorer plate is a small chunk of the Juan de Fuca plate that broke away from the Juan de Fuca plate about 3.5 Ma and has moved much slower ...
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 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.
Aerial view taken on February 28, 2021 shows the "Bridge between Continents", a footbridge linking the Eurasian and North American tectonic plates, near the town of Grindavik on the Reykjanes ...
One of the smallest of Earth's tectonic plates, the Juan de Fuca plate is a remnant part of the once-vast Farallon plate, which is now largely subducted underneath the North American plate. In plate tectonic reconstructions, the Juan de Fuca plate is referred to as the Vancouver plate between the break-up of the Farallon plate c. 55–52 Ma and ...
