When oceanic lithosphere collides with another oceanic plate the ___ In the process of subduction?
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.
Why do oceanic lithospheric plates sink at subduction zones?
Young oceanic lithosphere is hot and buoyant (low density) when it forms at a midocean ridge. But as it spreads away from the ridge and cools and contracts (becomse denser) it is able to sink into the hotter underlying mantle. There is a deep ocean trench where the oceanic plate bends downward.
What happens to the lithosphere when it Subducts?
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.
Where is one plate being subducted under another?
subduction zone Such destruction (recycling) of crust takes place along convergent boundaries where plates are moving toward each other, and sometimes one plate sinks (is subducted) under another. The location where sinking of a plate occurs is called a subduction zone.
What happens when oceanic and oceanic plates 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.
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 oceanic lithosphere and continental lithosphere collide?
What happens when oceanic and continental lithosphere collide? Magma forms the asthenosphere cools to form new oceanic lothosphere.
What happens when continental and oceanic lithosphere collide?
when oceanic lithosphere collides with continental lithosphere oceanic subducts because it's denser than continental lithosphere. when two plates are made of oceanic lithosphere and collide one plate is subducted under the other forming deep ocean trench.
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.
What happens when 2 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 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.
Where oceanic lithosphere is colliding with continental lithosphere?
oceanic – continental lithosphere: A good example is at the trench along the west coast of the South American continent where oceanic lithosphere of the Pacific (actually the small Nazca plate) is being subducted (sinking) eastward beneath the South American plate and continent.
What is formed when oceanic plate collides with the continental plate?
Click on a diagram on the right to learn more. 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 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.
Which is formed when oceanic plate collides with continental plate?

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.
What would happen if an oceanic plate collides with an 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. Examples include the Mariana Islands in the western Pacific Ocean and the Aleutian Islands, off the coast of Alaska.
What happens when oceanic oceanic plates 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 the oceanic plate is?
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 happens at a convergent plate boundary when an oceanic plate collides with an oceanic plate?
Ocean-Ocean Convergence Two oceanic plates may collide. In this case, the older plate is denser. This plate subducts beneath the younger plate. As the subducting plate is pushed deeper into the mantle, it melts.
