What landforms do oceanic-oceanic boundaries form?
Volcanoes and island arcs
When are island-arc volcanoes formed?
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
When are island arc volcanoes formed?
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
Why isn't new oceanic crust generated along volcanic island arcs?
At a volcanic island arc, an oceanic plate slides into the mantle and thus oceanic crust is destroyed. The volcanoes add material on to of the crust, but to not cause the crust to expand outward.
What process forms island arcs?
Island arcs are formed from the subduction and melting of oceanic crust as it descends into the mantle underneath a less dense oceanic crust at a convergent plate boundary. The subduction results in the creation of undersea volcanoes which then rise above sea level. The resulting volcanoes create a string of islands called an island arc. The curve of an island arc echoes the curve of its deep-ocean trench.

What are formed when two oceanic plates collide?
volcanoes in an island arc
When Volcanoes found where two oceanic plates collide form at a what?
Island Arcs
What is volcanic island arc?
I think its a chain of volcanoes form when oceanic crust subducts beneath other oceanic crust on an adjacent plate. Hope this helps (:

What is the lava in mid oceanic volcanoes made of?
All lava is the same- molten(liquid) rock

Volcanoes at boundaries where two oceanic plates collide create a string of islands called?
Volcanoes at the boundaries where two oceanic plates collide will create a string of islands called an archipelago. An archipelago is also linked by land areas that are below the sea.
What happens at a oceanic oceanic convergence?
At an ocean ocean convergent boundary, there will be a formation of volcanoes.
What happens when two crusts collide?
When two crustal plates are in the process of collision they deform, the results of which vary:continental-continental, large mountain building (e.g. asia-india building the himalayas)oceanic-oceanic, island arc building with volcanic islands (e.g. the Japanese islands)oceanic-continental, subduction of oceanic plate under continental plate with inland volcanoes (e.g. volcanoes in Washington, Oregon, and northern California)
