What Geographic Feature Is Associated With An Ocean Plate Going Under A Continental Plate??

Oceanic trenches are formed at subduction zones. Oceanic plates meet continental plates in the water, so trenches are formed as the oceanic plate goes under the continental plate. These trenches can be very deep if the plate that is subducting (going down) is an older and colder plate.Apr 24, 2017

What is it called when an oceanic plate goes under a continental plate?

Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches.

What happens when an oceanic plate goes under a continental plate?

When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate. … As time goes on the hot magma rising upward from the subduction zone causes further compression of the mountain belt.

What feature is associated with a continental plate boundary?

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.

Which geographic features form as a result of continental continental?

What features are the result of a continental-continental convergent boundary? Denser oceanic lithosphere subducts (sinks) under the less dense continental lithosphere which can create a volcanic arc, lithosphere can be recycled, subduction zones are created under the earth, deep ocean trenches can also be created.

Is a defining feature of an oceanic plate?

Oceanic plates are mafic in nature, composed of basalt rock and its coarse-grained equivalent, gabbro, both rich in iron, magnesium and calcium. In contrast, continental plates are felsic in nature, dominated by granitic rock with its abundant silica, aluminum, sodium and potassium.

Which is formed when an oceanic plate converges with another oceanic plate?

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 features would you expect to find at an ocean continent convergent plate boundary?

At a convergent plate boundary, when one plate is oceanic, there are large volcanoes. These volcanoes are found in lines that outline the subduction zone. Earthquakes also happen in these zones. The Aleutian Islands that border southern Alaska are an island arc.

What is an oceanic oceanic convergent boundary?

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). … It mixes with the overlying mantle, and the addition of water to the hot mantle lowers the crust’s melting point and leads to the formation of magma (flux melting).

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.

Which of the following is a feature of a continental continental convergent plate boundary?

If the two plates that meet at a convergent plate boundary both consist of continental crust, they will smash together and push upwards to create mountains. Large slabs of lithosphere smashing together create large earthquakes.

Which surface feature is associated with continental continental convergent plate boundary?

The Geological features that are associated with convergent plate boundaries are Mountains, Trenches, Island Arcs, Volcanoes & Terranes.

Which geographic features are associated with a divergent boundary?

A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.

What is convergent continental continental plate boundary?

A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. … Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere.

Which geologic feature results the convergence of continental and oceanic crusts?

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.

Where is an example of a continental continental plate boundary?

Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran.

Is the Antarctic plate oceanic or continental?

The Antarctic Plate includes continental crust making up Antarctica and its continental shelf, along with oceanic crust beneath the seas surrounding Antarctica.

What makes a continental plate continental?

The answer lies in the composition of the rocks. Continental crust is composed of granitic rocks which are made up of relatively lightweight minerals such as quartz and feldspar. By contrast, oceanic crust is composed of basaltic rocks, which are much denser and heavier.

Is continental or oceanic plate denser?

Both oceanic crust and continental crust are less dense than the mantle, but oceanic crust is denser than continental crust. This is partly why the continents are at a higher elevation than the ocean floor.

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.

What geologic process produces oceanic trench?

subduction

In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

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 would you expect to find at ocean ocean convergence?

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.

Which of the following is a geographic example of a transform plate boundary?

The most famous example of this is the San Andreas Fault Zone of western North America. The San Andreas connects a divergent boundary in the Gulf of California with the Cascadia subduction zone. Another example of a transform boundary on land is the Alpine Fault of New Zealand.

What landforms are created by oceanic oceanic?

A guyot is an underwater mountain range and a seamount is the a deep part of the ocean between guyots. A guyot is an underwater mountain with a flat top and a seamount is an underwater mountain with a peak.

What happens at a continental oceanic boundary?

When continental and oceanic plates collide, the thinner and more dense oceanic plate is overridden by the thicker and less dense continental plate. The oceanic plate is forced down into the mantle in a process known as “subduction.” As the oceanic plate descends, it is forced into higher temperature environments.

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 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.

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.

What geologic features are formed in continental continental convergence?

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. The Appalachian Mountains resulted from ancient convergence when Pangaea came together.
