Question: What Is An Example Of Oceanic Oceanic Convergence?

What are the examples of convergent boundaries?

Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Mountains and the Peru Trench) and subduction of the Juan de Fuca Plate under North America (creating the Cascade Range)..

What are the characteristics of oceanic plate?

oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The material that is poured out are basaltic lave in nature. Basalt is denser and heavier than the granite that makes up continental plates. Oceanic plates are much thinner than the continental plates.

Where are oceanic oceanic convergent boundaries found?

Examples of ocean-ocean convergent zones are subduction of the Pacific Plate south of Alaska (creating the Aleutian Islands) and under the Philippine Plate, where it creates the Marianas Trench, the deepest part of the ocean.

What is the example of convergent?

An example of convergent evolution is the similar nature of the flight/wings of insects, birds, pterosaurs, and bats. All four serve the same function and are similar in structure, but each evolved independently.

What is oceanic oceanic convergence?

Oceanic – oceanic convergence In collisions between two oceanic plates, the cooler, denser oceanic lithosphere sinks beneath the warmer, less dense oceanic lithosphere. As the slab sinks deeper into the mantle, it releases water from dehydration of hydrous minerals in the oceanic crust.

What 3 things are created by Convergent boundaries of oceanic and oceanic crust?

When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions.

What happens when Oceanic and Oceanic collide?

When two oceanic plates collide one oceanic plate is eventually subducted under the other. … This andesitic magma is formed from the partial melting of the asthenosphere just above the subduction zone. This partial melting of the subducting plate is due to the loss of water as it descends into the mantle.

What is the difference between continental and oceanic crust?

It is the solid rock layer upon which we live. It is either continental or oceanic. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. Oceanic crust is denser, can be subducted and is constantly being destroyed and replaced at plate boundaries.

What landforms are created by Oceanic Oceanic?

Landforms under the ocean are:continental shelf,continental slope,continental rise,abyssal plain,mid-ocean ridge,rift zone,trench,seamount/guyot.

What are the major oceanic plates?

The current continental and oceanic plates include: the Eurasian plate, Australian-Indian plate, Philippine plate, Pacific plate, Juan de Fuca plate, Nazca plate, Cocos plate, North American plate, Caribbean plate, South American plate, African plate, Arabian plate, the Antarctic plate, and the Scotia plate.

What happens when two oceanic plates transform?

When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.

What happens when two continents collide?

What happens when two continental plates collide? … Instead, a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges.

What happens when two oceanic plates collide Brainly?

Answer. When two oceanic plates collide one oceanic plate is eventually subducted under the other. Where one plate slides under the other is referred to as the ‘subduction zone’. As the subducting plate descends into the mantle where it is being gradually heated a benioff zone is formed.

What is an example of oceanic plate?

An example of an oceanic plate is the Pacific Plate, which extends from the East Pacific Rise to the deep-sea trenches bordering the western part of the Pacific basin. A continental plate is exemplified by the North American Plate, which includes North America as well as the oceanic crust…

What are the roles of oceanic plates?

Oceanic plates are formed by divergent plate boundaries. These zones, located along mid-ocean ridges, represent areas where upwelling magma creates new oceanic crust. … As oceanic plates subduct, they melt to form magma. This magma cools over millions of years, producing intrusive igneous rock and new continental crust.

What happens when two oceanic plates diverge?

When two oceanic plates diverge, underwater ridges and mountain ranges form, such as the mid-Atlantic Ridge. You can think of this like the formation of underwater volcanoes, though it is a more gradual process. Eventually these mountain ranges can rise above the water to form islands.

What are 2 examples of divergent boundaries?

ExamplesMid-Atlantic Ridge.Red Sea Rift.Baikal Rift Zone.East African Rift.East Pacific Rise.Gakkel Ridge.Galapagos Rise.Explorer Ridge.More items…

What landforms are created by convergent boundaries?

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
