A ____ Forms Where Two Oceanic Plates Collide

A ____ Forms Where Two Oceanic Plates Collide?

A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.

What happens when two oceanic plates collide answer?

When two oceanic plates converge the denser plate will end up sinking below the less dense plate leading to the formation of an oceanic subduction zone. … Whenever a subduction zone is formed the subducted plate will end up being partially melted by the earth’s internal magma and molten.

When two plates collide it is called a?

When two plates come together it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.

What happens when oceanic and oceanic collide?

Ocean-Ocean Collisions

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 happens when two oceanic plates collide quizlet?

When two oceanic plates collide the denser plate is subducted and some material rises upward and forms an ISLAND. … Ocean floor is pushed away from a midocean ridge to form new sea floor.

What is formed when oceanic and continental plates collide?

When an ocean plate collides with another ocean plate or with a plate carrying continents one plate will bend and slide under the other. This process is called subduction. A deep ocean trench forms at this subduction boundary.

What type of plates collide in oceanic oceanic convergence?

An oceanic convergent plate boundary forms where two plates collide. In these collisions one plate sinks beneath the other. A subduction zone forms along the boundary where the denser plate sinks into the mantle and is heated causing plumes of molten magma to rise upward through the top plate.

When a continental plate and an oceanic plate collide they can form quizlet?

When 2 continental plates collide neither sink because they both have similar density in each. They will form mountain ranges. When both a oceanic and continental collide the oceanic plate will subduct under the continental because it is more dense a deep sea trench will usually form.

Where is a oceanic to oceanic convergent boundary?

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.

Which of the following is form in the convergence of two oceanic oceanic and continental plates?

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 subducting plate causes melting in the mantle above the plate. The magma rises and erupts creating volcanoes.

Which of the following is form when two continental plates collide?


When continental plates collide mountains form. The least understood of all tectonic boundaries continental plates have greater density sometimes reaching lower than the mantel. When these plates collide it’s reminiscent of the force of two bulls butting heads.

What is created when two oceanic plates converge?

Oceanic-oceanic convergence

As with oceanic-continental convergence when two oceanic plates converge one is usually subducted under the other and in the process a trench is formed. … Subduction processes in oceanic-oceanic plate convergence also result in the formation of volcanoes.

When two oceanic plates come together A is formed quizlet?

When two oceanic plates collides they will form a volcanic island arc. This also forms a subduction zone. This is happening at the Aleutian Islands close to Alaska. Boundary between tectonic plates in which the two plates move away from each other and new crust is created between them.

Are formed when two continental plates collide quizlet?

What happens at convergent boundaries where two continental plates collide? 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 is formed from the collision?

In order for a collision to be successful by resulting in a chemical reaction A and B must collide with sufficient energy to break chemical bonds. This is because in any chemical reaction chemical bonds in the reactants are broken and new bonds in the products are formed.

What happens when two crusts collide?

When two plates with continental crust collide they will crumple and fold the rock between them. A plate with older denser oceanic crust will sink beneath another plate. The crust melts in the asthenosphere and is destroyed.

When oceanic lithosphere collides with another plate?

When two oceanic lithospheres collide one runs over the other which causes the latter to sink into the mantle along a zone called a subduction zone. The subducting lithosphere is bent downward to form a very deep depression in the ocean floor called a trench. The deepest ocean in the world is found along trenches.

Is Japan a oceanic oceanic convergent boundary?

Japan has been situated in the convergent plate boundary during long geohistorical ages. This means that the Japanese islands are built under the subduction tectonics. The oceanic plate consists of the oceanic crust and a part of the mantle beneath it.

How are oceanic oceanic and oceanic continental convergent boundaries different?

The oceanic plate is pushed under the continental plate and melted. … Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates.

What happens when an oceanic plate meets another oceanic plate quizlet?

The oceanic plate is subducted. What happens when an oceanic plate meets another oceanic plate? The older colder oceanic plate is subducted. … The two plates are forced upward and a large mountain range is formed.

What forms when one oceanic plate subducts under another oceanic plate?

The volcanic arcs may be volcanic island arcs (e.g. Aleutians Mariannas) where one oceanic plate subducts beneath another oceanic plate or continental volcanic arcs (e.g. Andes Cascades) where oceanic plates subduct under a continental plate.

What does oceanic oceanic convergence?

In ocean-ocean convergence two oceanic plates converge or collide. The denser plate subducts into the asthenosphere below the convergence zone and forms a trench at the surface. This region below the convergence zone is called the zone of subduction.

Why volcanoes are formed in converging two oceanic plates and in convergent oceanic continental plate?

Melting. Melting at convergent plate boundaries has many causes. … As the sediments subduct the water rises into the overlying mantle material and lowers its melting point. Melting in the mantle above the subducting plate leads to volcanoes within an island or continental arc.

Which of the following is formed in the convergence of two continental plates converge?


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. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.

When an oceanic and a continental plate meet A is formed on the oceanic side and are formed on the continental side?


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 (figure 6). The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions.

What forms when one oceanic plate is forced beneath another plate?

When one oceanic plate is forced beneath another plate a subduction zone is formed.

What happens in a collision plate boundary?

The plates move towards one another and this movement can cause earthquakes and volcanoes. … If two continental plates collide neither can sink and so the land buckles upwards to form fold mountains. This is called a collision boundary . Earthquakes can occur at collision boundaries.

What happens to plate A as it collides with plate B?

Answer: The volcanic arc is formed to “plate A” as it collides with “plate B”. The collision of these two plates results in the oceanic current which is generated. … The earthquake is produced because of the volcanic arc creation between the plate A and the plate B.

What are the landforms created after the collision?

Collisions of two plates may create everything from fold mountains to oceanic trenches divergent plates come marked by mid-ocean ridges.

What happens when two plates slide each other?

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 happened to the oceanic lithosphere or plate?

Seafloor Processes

Oceanic lithosphere forms at midocean ridges where hot magma upwells and then cools to form plates as the material moves away from the spreading center.

Which of the following is where two lithospheric plates collide with one plate eventually sliding beneath the other causing a process known as subduction?

A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other a process known as subduction.

What happens to the lithospheric plates as they collide with each other?

Convergent boundaries: where two plates are colliding.

Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. The denser plate is subducted underneath the less dense plate. The plate being forced under is eventually melted and destroyed.

What geologic features are formed in oceanic oceanic convergence?

When two oceanic plates converge both a trench and a string of volcanoes are formed. These volcanoes can build to produce island chains such as the Mariana Islands which are located alongside the Marianas Trench.
