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.
What happens at a convergent boundary between two oceanic plates?
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt . Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Where on earth will you find a convergent boundary between two oceanic plates?
We continue our trip up western North America to find a convergent plate boundary where oceanic crust subducts beneath oceanic crust. North of the contiguous U.S. lies Canada, and north of Canada lies Alaska. A line of volcanoes, known as the Aleutian Islands, is the result of ocean – ocean convergence.
What 3 things are created by Convergent boundaries of oceanic and oceanic crust?
Covers ocean-ocean and ocean-continent convergent plate boundaries, including the creation of volcanic arcs and earthquakes .
What do oceanic oceanic convergent boundaries form?
Oceanic/Oceanic Convergent Boundaries
Such a convergent boundary includes a seafloor trench marking the earthquake-rattled subduction zone as well as an island arc: a line of volcanoes created by rock-melt in the mantle associated with subduction.
Which is the best example of a convergent plate boundary?
Answer: The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.
What landforms are created by convergent boundaries?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
Do convergent boundaries form mountains?
Mountains are usually formed at what are called convergent plate boundaries , meaning a boundary at which two plates are moving towards one another. ... Sometimes, the two tectonic plates press up against each other, causing the land to lift into mountainous forms as the plates continue to collide.
What are the three types of convergent boundaries?
Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.
Do convergent boundaries cause volcanoes?
Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other. Volcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate.
Is Japan a oceanic oceanic convergent boundary?
Japan has been situated in the convergent plate boundary during long geohistorical ages. ... The oceanic plate consists of the oceanic crust and a part of the mantle beneath it. The oceanic crust brings basaltic lava, deep marine sediments, seamounts and so on.
What are examples of transform boundaries?
Some transform plate boundaries pass through continental crust. An example of such a transform is the San Andreas Fault . Along the San Andreas Fault the Pacific plate moves in a northwest direction relative to the North American plate.
Where are most convergent plate boundaries found?
Two locations are marked to show this type of plate boundary – the Cascade volcanoes along the Washington-Oregon coast of North America and the Andes mountain range on the western margin of South America.
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 landforms are created by oceanic-oceanic?

What is the difference between a convergent and divergent boundary?
Divergent boundaries — where new crust is generated as the plates pull away from each other . Convergent boundaries — where crust is destroyed as one plate dives under another.
