What type of plate boundary is the Cocos Plate?

This subduction-subduction-transform (SST) triple junction is referred to hereafter as the NACC triple junction. Off the Pacific coast, the Cocos plate is subducted beneath both the North American and Caribbean plates, which are separated by a sinistral transcurrent boundary.

Is the Cocos Plate convergent or divergent?

Compared to the other tectonic plates in the region, the Cocos Plate is converging with the Caribbean Plate at a steady rate of about 78 millimeters per year based on data from ISCO over 10 months.

What type of plate boundary is between the Nazca and Cocos Plate?

Peru–Chile Trench

The northern side is a divergent boundary with the Cocos Plate, the Galapagos Rise. The subduction of the Nazca plate under southern Chile has a history of producing massive earthquakes, including the largest ever recorded on earth, the moment magnitude 9.5 1960 Valdivia earthquake.

Is the Cocos Plate subduction?

The Central American Case

Regional tectonics of Central America are mainly controlled by the collision of the Cocos and the Caribbean plates. As a result of this collision, the oceanic Cocos plate is subducted below the Caribbean along the Mesoamerican trench plate at speeds ranging from 2 in.

How was Cocos ridge formed?

The Cocos Ridge (CR), which formed when the Cocos Plate drifted over the Galapagos Hotspot (Walther, 2003) , is a bathymetric high reaching about 2 km above the surrounding seafloor and stretching about 2000 km long and 200-300 km wide across the Cocos Plate .

What is the Cocos Plate made of?

The Cocos Plate is a young oceanic tectonic plate beneath the Pacific Ocean off the west coast of Central America, named for Cocos Island, which rides upon it.

What type of boundary is the Philippine plate?

This highly active convergent plate boundary extends along both sides the Philippine Islands, from Luzon in the north to the Celebes Islands in the south.

What plate boundary is the Philippines and Eurasian Plate?

Taiwan area is the collision boundary between the Philippine Sea plate and the Eurasia plate, which has complex interaction, attracting much attention[30−33].

Is Philippines in the Eurasian Plate?

The Philippine Plate, also known as the Philippine Sea Plate, is a small tectonic plate between the Eurasian Plate and the Pacific Plate. The Philippine Sea Plate has an area of approximately 3400 square kilometers.

What is a divergent 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.

What are the 4 types of plate boundaries?

Tectonic Plates and Plate Boundaries

• Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. …
• Divergent boundaries – where two plates are moving apart. …
• Transform boundaries – where plates slide passed each other.

What are convergent boundaries?

A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

What is the example of transform boundary?

The most famous example of a transform boundary is the San Andreas Fault in California. The west side of California is moving north, and the east side is moving south.

What are the three types of convergent plate boundaries?

Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.

What type of boundary is the San Andreas Fault?

The 1,200-kilometer-long San Andreas fault zone is part of the boundary between the Pacific and North American plates, and thus is known as a transform fault.

Are transform boundaries continental or oceanic?

Transform faults are not limited to oceanic crust and spreading centers; many of them are on continental margins. The best example is the San Andreas Fault on the Pacific coast of the United States.

Where are transform plate boundaries?

Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California’s San Andreas fault is a transform boundary.

Where is a divergent plate boundary located?

mid-ocean oceanic ridges

Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).

What plate boundary shows the collision of two plates?

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction.

Is the Nazca plate convergent or divergent?

convergent boundaries

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.

Is the Nazca Plate a convergent boundary?

The Nazca plate is an oceanic tectonic plate in the southeastern Pacific Ocean that shares both convergent and divergent boundaries, corners multiple triple junctions, contains three seamount chains, overrides four hotspots, and is responsible for the creation of the Andean orogeny (Figure 1).

Is the Philippine plate convergent or divergent?

convergent

The Philippine Sea Plate. The Philippine Sea plate is tectonically unusual in that almost all the boundaries are convergent. The Pacific plate is subducting beneath the Philippine Sea plate to the east while the west/northwestern part of the Philippine Sea plate is subducting beneath the continental Eurasian plate.

What plate boundary is Nazca Plate?

What caused the Chile earthquake of 1960? The Nazca plate is a large tectonic plate that underlies the Pacific Ocean near the western coast of South America. It is subducting under (that is, being forced under) the South American plate.

What type of plate boundary is Antarctic and Australian plate?

divergent boundary

The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia.

What type of plate boundary is North American and Eurasian Plates?

divergent plate boundary

All volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell, the 1783 eruption of Laki, and the 2010 eruption of Eyjafjallajökull, are caused by the North American and the Eurasian Plates moving apart, which is a result of divergent plate boundary forces.
