|Plate name||Description of plate|
|North America Plate||This plate includes all of North America, Greenland, the eastern most part of Russia, northern Japan, and the northwestern part of the Atlantic ocean.|
|Pacific plate||This plate makes up most of the Pacific Ocean.|
|North American Plate|
|Speed1||15–25 mm (0.59–0.98 in)/year|
Earthquakes occur around mid-ocean ridges and the large faults which mark the edges of the plates. The World Atlas names seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
plate is exemplified by the North American Plate, which includes North America as well as the oceanic crust between it and a portion of the Mid-Atlantic Ridge.
The Pacific Plate is being moved north west due to sea floor spreading from the East Pacific Rise (divergent margin) in the Gulf of California. The North American Plate is being pushed west and north west due to sea floor spreading from the Mid Atlantic Ridge (divergent margin).
Today, about 95% of the Antarctic plate is surrounded by divergent plate boundaries: the Southwest Indian Ridge, the Southeast Indian Ridge, and the American-Antarctica Ridge.
Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Range) and subduction of the Juan de Fuca Plate under North America (creating the mountains Garibaldi, Baker, St.
|South American Plate|
|Approximate area||43,600,000 km2 (16,800,000 sq mi)|
|Speed1||27–34 mm (1.1–1.3 in)/year|
To the east, the North American plate shares the Mid-Atlantic Ridge with the Eurasian plate. This divergent margin, offset throughout by transform faults, began spreading approximately 180 Ma ago, opening the North Atlantic Ocean (Kearey, 2009).
South American plate is a relatively large sized plate located below the continent, South America. South American plate is bounded by African plate in the east, Nazca plate in the west, Antarctic plate and Scotia plate in the south, and Caribbean plate and North American plate in the north.
There are two kinds of plates – oceanic and continental plates. When oceanic and continental plates meet, the denser oceanic plate moves under the less dense continental plate. The Australian plate is a continental plate and the Pacific plate is an oceanic plate.
It’s estimated that the Antarctica major plate moves about 1 cm per year. As for its size, it’s the fifth largest tectonic plate on the planet at about 60,900,000 km2.
The two longest boundaries—those with the Antarctic and South American plates—are both sinistral strike-slip boundaries (Thomas et al., 2003). The southern border with the Antarctic plate, known as the South Scotia Ridge, moves with a rate of 7.5-9.5 mm/yr.
transform plate boundary
The transform plate boundary between the Pacific and North American Plates in western California formed fairly recently. About 200 million years ago, a large tectonic plate (called the Farallon Plate) started to subduct beneath the western edge of North America.Feb 11, 2020
The coastal area of Nigeria lies in close proximity to the boundary between the African plate and South American plate.May 17, 2011
The Antarctic Plate includes continental crust making up Antarctica and its continental shelf, along with oceanic crust beneath the seas surrounding Antarctica.
two of these plates—the continental South American Plate and the oceanic Nazca Plate—gave rise to the orogenic (mountain-building) activity that produced the Andes.
The San Andreas Fault is where the Pacific plate collides with the North American plate. this is a convergent boundary.
It divides California into two in which San Diego, Los Angeles, and Big Sur are on the Pacific Plate, whereas Sacramento, San Francisco, and the Sierra Nevada are on the North American Plate.
