What forms when one oceanic plate is forced beneath another plate quizlet?
This process is called subduction. A deep ocean trench forms at this subduction boundary.
What is it called when one plate is pushed beneath another?
Oceanic-Oceanic Subduction An occurs where one plate with oceanic crust sinks, or subducts, under another plate with oceanic crust. The older plate sinks because it is colder and denser than the younger plate.
What feature forms when one oceanic plate subducts beneath another?
Deep trenches 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 at subduction zones as well.
When one plate is forced beneath another into the mantle?
Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones the edge of the denser plate subducts or slides beneath the less-dense one. The denser lithospheric material then melts back into the Earth's mantle.
What occurs when an oceanic plate dives below continental plates?
At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust. (Sometimes, oceanic crust may grow so old and that dense that it collapses and spontaneously forms a subduction zone, scientists think.)
What happens when an oceanic plate collides with a continental plate quizlet?
What happens when an oceanic plate and a continental plate collide? Oceanic plate is subducted and some of the material rises upward and erupts as VOLCANO.
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. Examples include the Mariana Islands in the western Pacific Ocean and the Aleutian Islands, off the coast of Alaska.
What happens when one plate goes under another?
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. A deep ocean trench forms at this subduction boundary.
What happens when one tectonic plate is forced beneath another?
In some cases, however, a convergent plate boundary can result in one tectonic plate diving underneath another. This process, called “subduction,” involves an older, denser tectonic plate being forced deep into the planet underneath a younger, less-dense tectonic plate.
What happens when an oceanic plate meets 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.
Why is the oceanic plate forced under continental plate?
When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.
When an oceanic and a continental plate meet what is formed?
Ocean-Continent Convergence. 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.
What happens when a oceanic and oceanic plate collide?
When two oceanic plates converge, the cooler, denser one descends, or subducts, beneath the overriding plate and sinks into the mantle. When an oceanic plate meets a plate with a continent riding atop it, the oceanic plate is again subducted.
When an oceanic plate collides with a continental plate?
When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.
What does oceanic oceanic form?
Oceanic-Oceanic Convergent Boundary At a convergent boundary between two plates of oceanic lithosphere, the older, denser oceanic plate will always subduct, which will cause earthquakes and form volcanic isles.
What forms when two oceanic plates diverge?
Divergent boundaries in the middle of the ocean contribute to seafloor spreading. As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge.

What does oceanic oceanic convergence create?
Ocean-Ocean Convergence As the subducting plate is pushed deeper into the mantle, it melts. The magma this creates rises and erupts. This forms a line of volcanoes, known as an island arc (Figure below).
What is formed 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. Examples include the Mariana Islands in the western Pacific Ocean and the Aleutian Islands, off the coast of Alaska.
When oceanic and continental plates collide What is the result?
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. Once again a benioff zone forms where there are shallow intermediate and deep focus earthquakes.
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.
When an oceanic and continental plates meet what is formed?
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.
