What Forms When One Oceanic Plate Is Forced Beneath Another Plate?

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.

When a plate is forced beneath another plate?

Where two tectonic plates meet at a subduction zone one bends and slides underneath the other curving down into the mantle. (The mantle is the hotter layer under the crust.)

What landform results when an oceanic plate is forced beneath 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 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.

When an oceanic plate and continental plate collide which plate will be force down into the mantle?

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 landforms are created at oceanic oceanic convergent boundaries?

An ocean-ocean convergent boundary occurs location where two oceanic plates come together and the denser plate sinks or subducts beneath the less dense plate forming a deep ocean trench. Chains of volcanoes called island arcs form over subduction zone melting occurs where the subducting plate reenters the mantle.

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 is it called when one plate is pushed under another plate as they collide?

Plates Subduct. 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.

What type of plates collide in oceanic oceanic convergence?

At an ocean-ocean convergent boundary one of the plates (oceanic crust and lithospheric mantle) is pushed or subducted under the other (Figure 4.6. 1). Often it is the older and colder plate that is denser and subducts beneath the younger and warmer plate.

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 geologic feature is formed when two oceanic plates collide?

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.

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.

When the oceanic plate hits a continental one the continental plate?

Generally when the oceanic plate hits a continental one the continental plate uplifts and the oceanic plate goes beneath it or subducts. When two oceanic plates collide the older heavier plate usually subducts beneath the other.

Which of the following is formed in the convergence of two oceanic or 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.

When an oceanic 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.

Which landform would most likely be created when two oceanic plates converge?

Which landform would most likely be created when two oceanic plates converge? A volcanic island arc.

Which is an example of the features formed at oceanic oceanic convergence?

An example of an oceanic/oceanic convergent boundary is that between the Pacific and Mariana plates which includes the Mariana Islands arc and a subduction zone encompassing the Mariana Trench the deepest part of the World Ocean.

What forces responsible for the movement of plates?

Heat and gravity are fundamental to the process

Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces.

What happens to the leading plate as it thrust beneath another plate?

Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth’s mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate the heavier plate dives beneath the second plate and sinks into the mantle.

What happens during sea floor spreading?

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises often forming a mountain or elevated area of the seafloor. Eventually the crust cracks.

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.

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 does a convergent ocean ocean plate collision makes?

Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes volcanic activity and crustal deformation.

What forms when an oceanic plate and a continental plate converge *?

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. … Subduction of an oceanic plate beneath a continental plate causes earthquakes and forms a line of volcanoes known as a continental arc.

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 happens when the two plates collide slide past with each other move opposite from 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 is formed from the collision of oceanic continental?

Ocean-Continent Convergence

This occurs at an ocean trench (Figure below). Subduction zones are where subduction takes place. Subduction of an oceanic plate beneath a continental plate forms a line of volcanoes known as a continental arc and causes earthquakes.

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 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.

What events occur during the convergent of continental plates and oceanic plates?

When a continental plate meets an oceanic plate the thinner denser and more flexible oceanic plate sinks beneath the thicker more rigid continental plate. This is called subduction. Subduction causes deep ocean trenches to form such as the one along the west coast of South America.

What type of mountain is most likely to form when two oceanic plates collide?

Terms in this set (20)

What type of mountain is most likely to form when plates with edges that have oceanic lithosphere collide? plateaus. What is the term for the amount of force that changes the shape and volume of rock? A mountain that forms where rock layers are squeezed and uplifted.

What forms when two tectonic plates of different densities collide?

When plates of differing densities collide the plate that is more dense goes under the less dense plate. Trenches and volcanic mountains form.

What is formed during the convergence of two continental plates?

When two continental plates converge they smash together and create mountains. The amazing Himalaya Mountains are the result of this type of convergent plate boundary.

What are formed in oceanic oceanic?

The features of an ocean-ocean subduction zone are the same as those of an ocean-continent subduction zone except that the volcanic arc will be a set of islands known as an island arc. The older plate subducts into a trench resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.
