Yes! When two oceanic plates collide, one of the plates subducts beneath the other. As the subducting plate sinks, it releases volatiles (such as carbon dioxide and water) into the mantle. This addition causes the mantle to melt in the places where it mixes with volatiles. The melted mantle is less dense than the surrounding mantle, so it slowly rises until it reaches the surface. When the melted mantle reaches the surface, it is considered a volcano. Over many years, these volcanoes build up the sea floor and may eventually break the surface. Now, these volcanoes have become volcanic islands, and usually occur as a string (an arc) of volcanic islands that follow the plate boundary.

Forms when two Crustal Lithospheric Plates come together?
The Convergent/Converging Boundaries
What do convergent plate boundary form?
Convergent plate boundaries can occur as a continental-continental, continental-oceanic, or oceanic-oceanic crust collision. A continental-continental collisions will typically result in a mountain range formation, such as the Himalayan Mountain Range. A continental-oceanic converging plate boundary will result in the more dense oceanic crust subducting beneath the less dense continental crust. The subduction zone leads to volcano formation from melting rock within the asthenosphere, beneath the continental crust. An example of this boundary is the west coast of the United States. An oceanic-oceanic converging plate boundary will typically result in one oceanic slab "sliding" beneath the other, due to only slight differences in density. This may form a volcanic island arc on the ocean floor, but may not necessarily reach above sea level.
Plate tectonics what forms along continental divergent boundaries?
rift valley
Which volcanoes are located along colliding plate boundaries?
The East Pacific Rise is representative of a divergent boundary where the Pacific Plate and the Nazca Plate (west of South America) are moving apart—a process known as rifting. Volcanoes occur along both subduction and rift zones but are generally absent along strike-slip plate margins.
New oceanic lithosphere forms as a result of?
New oceanic lithosphere forms as a result of continental drift.
What are two ways volcanoes can forms near converging plate boundaries?
Volcanoes may form where two oceanic plates collide or where an oceanic plate collides with a continental plate.

The Convergent/Converging Boundaries
What feature forms at diverging oceanic plates?
Ridges of buoyant oceanic crust form at diverging oceanic plate boundaries.
Is true or false oceanic lithosphere is created at divergent boundaries?
Yes; at divergent/constructive boundaries, plates move apart and new oceanic lithosphere forms.
What forms on oceanic convergent boundaries?
I think its either a Trench or mountains/Volcanoes.
What forms where an oceanic plate begins to move down in a subduction zone?

At which plate boundaries do most volcanoes form?
Most volcanoes form at a convergent plate boundary. Simply put when a oceanic plate and a continental plate hit each other face on the subduction of the oceanic plate causes the magma to rise and the converging of the plates makes a mountain and the magma rises through the top creating a volcano.
Compare and contrast three different kinds of colliding boundaries?
Convergent boundaries involve two tectonic plates moving towards each other, resulting in the collision and subsequent formation of mountains or subduction zones. Examples include the collision of the Indian Plate with the Eurasian Plate to create the Himalayas. Divergent boundaries occur when two tectonic plates move away from each other, leading to the upwelling of magma and the formation of mid-ocean ridges. As the plates separate, new crust is formed at the boundary. An example is the Mid-Atlantic Ridge. Transform boundaries involve two tectonic plates sliding past each other horizontally, leading to earthquakes due to the friction between the plates. The San Andreas Fault in California is a well-known transform boundary.
What is the sea floor spreading theory?
Theory that oceanic crust forms along submarine mountain zones, known collectively as the oceanic ridge system, and spreads out laterally away from them.
