What is the North American Plate bounded by?
the Pacific Plate
In the east, the North American Plate is bounded by a subduction zone of the Pacific Plate that produced the active volcanoes of the Kurile-Kamchatka Arc.
Is the Pacific Plate under the North American Plate?
The largest one, the Pacific Plate is moving north west relative to the plate that holds North America, and relative to hot spots coming up through the mantle from below the plates (they generate islands like Hawaii).
Are the Pacific and North American plates convergent?
The Pacific Plate constitutes most of the seafloor of the Pacific Ocean. On its northern side, the Plate subducts under the North-American Plate, forming a convergent boundary and the Aleutian Trench along the islands of the same name.
Do the North American Plate and the Pacific Plate touch?
The San Andreas Fault, stretching along the central west coast of North America, is one of the most active faults on the Ring of Fire. It lies on the transform boundary between the North American Plate, which is moving south, and the Pacific Plate, which is moving north.
How old is North American Plate?
three billion years ago
As one of the Earth’s original continents, the North American Plate started forming some three billion years ago when the planet was much hotter and mantle convection much more vigorous. Roughly two billions years ago, the Earth cooled and these old floating pieces of the lithosphere, called cratons, stopped growing.
Which plate is the North American Plate?
The North American Plate is a tectonic plate covering most of North America, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores….

What type of plate is the North American Plate?
continental plate
continental plate 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.
Is the North American Plate splitting?
The faults cut through California land; as a result, the Pacific plate’s annual motion 6 cm north with respect to the North American plate in the area is actively splitting the state (Marshak, 2008; Atwater, 1970).
Is the North American Plate convergent or divergent?
Near Alaska, the North American Plate meets the Pacific Plate in a convergent boundary, meaning the plates are coming together. Here, the Pacific Plate sinks under the North American Plate in a process called subduction. As the Pacific Plate subducts, some pieces of the crust scrape off onto the North American Plate.
What are the boundaries of the North American Plate?
North American Plate. The North American Plate is a tectonic plate that underlies much of North America and Central America as well as part of the Caribbean Sea.It shares a boundary with the Pacific Plate and Cocos Plate in the west and the Caribbean Plate in the south.. On the northern boundary is a continuation of the Mid-Atlantic ridge called the Gakkel Ridge.
Is the Pacific Plate sliding past the North American Plate?
Today the Pacific Plate is sliding northwest relative to the North American Plate, much like the plate motion along the San Andreas Fault in California. However, many geologists believe that the plate motion was different in the past, with the Pacific Plate moving toward North America and sliding under the North American plate.
Which plate border the North American Plate?
a divergent boundary in the middle of the Atlantic Ocean, where the North American Plate borders the Eurasian Plate. This also created the Mid Atlantic Ridge, a chain of submarine ridges in the Atlantic. The North American Plate is moving west southwest about 2.3 cm per year.
What are the Pacific and North American plates?
– Panama Plate – Small tectonic plate in Central America – Gonâve Microplate – Part of the boundary between the North American Plate and the Caribbean Plate – South Jamaica Microplate – North Hispaniola Microplate – Puerto Rico-Virgin Islands Microplate
