What Happens When 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. … Earthquakes generated in a subduction zone can also give rise to tsunamis.
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 happens when two plates collide?
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.
What are the consequences of colliding oceanic plates?
Effects of a convergent boundary between an oceanic and continental plate include: a zone of earthquake activity that is shallow along the continent margin but deepens beneath the continent sometimes an ocean trench immediately off shore of the continent a line of volcanic eruptions a few hundred miles inland from …
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.
What does oceanic oceanic form?
Which is formed when oceanic plate converges with another oceanic plate?
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. … Old dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.
What is formed on the oceanic side when oceanic and continental collide?
A. Trench is formed on the oceanic side when oceanic and continental crust collide. Explanation: … At the subduction boundary a deep ocean trench forms.
What will happen if oceanic and continental crust interact with each other?
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.
What happens when the two plates collide slide past with each other move opposite from each other?
What happens with the old oceanic crust explain?
The oldest oceanic crust is about 260 million years old. … It is due to the process of subduction oceanic crust tends to get colder and denser with age as it spreads off the mid-ocean ridges. It gets so dense that it sinks in the upper mantle (subduction).
What is formed when an oceanic plate collides with a continental plate?
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. … The molten rock rises through the crust and erupts at the surface of the overriding plate.
What will most likely happen in convergence of two oceanic plates?
If the two plates that meet at a convergent plate boundary both are of oceanic crust the older denser plate will subduct beneath the less dense plate. … The older plate subducts into a trench resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.
When an oceanic plate converges with a continental plate quizlet?
What happens when an oceanic plate meets another oceanic plate? The older colder oceanic plate is subducted. What happens when a continental plate meets another continental plate? The two plates are forced upward and a large mountain range is formed.
What happens during oceanic oceanic convergence?
What happens to the surface of the ocean when an oceanic plate moves towards another oceanic plate?
At a convergent boundary with at least one oceanic plate an ocean trench a chain of volcanoes develops and many earthquakes occur. At a convergent boundary where both plates are continental mountain ranges grow and earthquakes are common.
What does oceanic oceanic convergence create?
Oceanic – Oceanic convergence – When two oceanic plates converge one is usually subducted under the other and in the process a deep oceanic trench is formed. The Marianas Trench for example is a deep trench created as the result of the Phillipine Plate subducting under the Pacific Plate.
Which of the following is formed in the convergence of two oceanic oceanic and continental plates?
When two oceanic plates collide against each other the older and therefore heavier of the two subducts beneath the other initiating volcanic activity in a manner similar to that which occurs at an oceanic-continental convergent plate boundary and forming a volcanic island arc.
Which of the following best describes what happens when an oceanic plate converges with a continental plate?
Which of the following best describes what happens when an oceanic plate converges with a continental plate? a trench and a mountain range with many volcanoes form. … Formed when an ocean basin between converging oceanic and continental plates is entirely subducted.
When two oceanic plates collide one runs over the other which causes it to sink into the mantle forming?
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.
When two tectonic plates collide the continental crust usually rise up over the oceanic crust because it is?
Oceanic crust is typically denser than continental crust and is forced downwards into the hot mantle when it collides with continental crust. The less dense conitinental crust is forced upward. This occurred in Ireland with the closure of the Iapetus Ocean over 450 million years ago.
What do you think may happen to oceanic plate as it continues to move downward?
As it continues to move downwards it will undergo subduction process. It will melt because of the very hot or high temperature of the mantle which is the layer below the crust.
What forms when two plates collide causing the crust to buckle and push upward?
Collision Zones and Mountains
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 during sea floor spreading?
Why is oceanic crust younger near the oceanic ridge and older closer to the two continents?
As magma that wells up from these rifts in Earth’s surface cools it becomes young oceanic crust. The age and density of oceanic crust increases with distance from mid-ocean ridges. … Largely due to subduction oceanic crust is much much younger than continental crust.
What happens when two continental plates collide quizlet?
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 happening when two plates are smashing into one another quizlet?
Convergent Plate Boundary. Place where two plates smash into each other. Oceanic-Oceanic Convergence. Occurs when two oceanic plates converge one is usually subducted under the other and in the process a deep. oceanic trench is formed.
What happen 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.
When an ocean plate converges with another plate what is created on the seafloor at the line of 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. The Marianas Trench (paralleling the Mariana Islands) for example marks where the fast-moving Pacific Plate converges against the slower moving Philippine Plate.
What geologic events take place with the convergence of two oceanic plates?
An oceanic-to-oceanic plate boundary occurs when two oceanic plates converge causing the older denser plate will subduct into the mantle. An ocean trench marks the location where the plate is pushed down into the mantle. The line of volcanoes that grows on the upper oceanic plate is an island arc.
What can happen when two oceanic plates converge and one is subducted into the mantle multiple choice question?
Where two tectonic plates converge if one or both of the plates is oceanic lithosphere a subduction zone will form. … As the ocean crust sinks deeper into the mantle the pressure increases (the temperature of the ocean crust rocks increases more slowly because rocks are poor conductors of heat).
Why does the oceanic crust sink?
(1) Oceanic crust has greater density.
What other geologic event could happen as the plates continuously grind each other?
At the “seams” where tectonic plates come in contact the crustal rocks may grind violently against each other causing earthquakes and volcano eruptions. The relatively fast movement of the tectonic plates under California explains the frequent earthquakes that occur there.
What other geologic event could take place with this type of plate movement?
Explanation: event like volcanic eruptions earthquakes and mountain formation could take place . During plate movement two plates meet at plate boundaries which are responsible for geological events.
