What type of plate boundary is found along the East Pacific ridge?
divergent”
The East Pacific Rise is a “divergent” plate boundary, where huge slabs of the Earth’s crust (plates) are moving away from each other.
Are the volcanoes of Hawaii part of the East Pacific Oceanic Ridge?
Which of the following energy sources is thought to drive the lateral motions of Earth’s lithospheric plates? The volcanoes of Hawaii are localized above a deep mantle hot spot; they are not part of the East Pacific oceanic ridge.
What plates are involved in the East Pacific Rise?
The East Pacific Rise is a mid-ocean ridge that runs through the eastern Pacific Ocean and separates the Pacific plate from the North American plate, the Cocos plate, the Nazca plate, and the Antarctic plate.
Where is the East Pacific Rift?
The East Pacific Rise is a mid-oceanic ridge, a divergent tectonic plate boundary located along the floor of the Pacific Ocean. It separates the Pacific Plate to the west from (north to south) the North American Plate, the Rivera Plate, the Cocos Plate, the Nazca Plate, and the Antarctic Plate.
What type of boundary is the Hawaiian Islands?
Convergent plate boundaries
Convergent plate boundaries are also called subduction zones and are typified by the Aleutian Trench, where the Pacific Plate is being subducted under the North American Plate.
Which of the following is an example of an oceanic oceanic divergent plate boundary?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
What type of plate boundary is Hawaii on?
Why is Hawaii in the middle of the Pacific Plate?
In areas where the plates come together, sometimes volcanoes will form. Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate.
Does the Pacific Ocean have a ridge?
The Pacific-Antarctic Ridge can be followed from a point midway between New Zealand and Antarctica northeast to where it joins the East Pacific Rise off the margin of South America. The former spreads at intermediate to fast rates.
What is the depth of East Pacific Rise?
The average depth to the ridge crest is ∼2500 m, but it rises above sea-level in Iceland and drops down more than 4000 m deep in the Cayman Trough.
How was the East Pacific ridge formed?
How is East Pacific Rise formed? The resulting underwater volcanoes spread lava across large areas of seafloor and form the core of the East Pacific Rise. Water percolating down into these lava flows is heated, then rises back toward the seafloor, forming hydrothermal (hot water) vents in the seafloor.
Is the Pacific Plate oceanic or continental?
oceanic
Because the Pacific Plate is entirely oceanic with no continents on which to establish a paleomagnetically determined plate motion history, APM models for the plate typically have been derived from the geometry and chronology of hot spot chains.
