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.

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 landforms do oceanic-oceanic boundaries form?
Oceanic-oceanic boundaries form features such as underwater mountain ranges known as mid-ocean ridges, deep-sea trenches, and volcanic island arcs. These boundaries are characterized by seafloor spreading and subduction processes that shape the Earth's crust and create dynamic geological features.
When oceanic lithosphere subducts beneath oceanic lithosphere?
The older, denser oceanic lithosphere will subduct beneath the younger, less dense oceanic lithosphere. This process can lead to the formation of deep ocean trenches, volcanic island arcs, and earthquakes. The descending plate may partially melt, contributing to the formation of magma that can erupt as volcanoes.

What are formed when two oceanic plates collide?
volcanoes in an island arc
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 island arcs for kids?
Island arcs are curved chains of volcanic islands that form along tectonic plate boundaries, usually where an oceanic plate is sliding under another plate. As the oceanic plate sinks, it melts and creates magma, which rises to the surface to form volcanoes. Over time, these volcanoes can build up to create islands. A well-known example of an island arc is the Japanese archipelago.
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 is a string of volcanoes along an ocean to ocean convergent boundary?
A string of volcanoes along an ocean-to-ocean convergent boundary is called a volcanic island arc. This forms when one oceanic plate subducts beneath another oceanic plate, leading to volcanic activity along the subduction zone. Examples include the Aleutian Islands in Alaska and the Japanese archipelago.
What happens at a oceanic oceanic convergence?
At an ocean ocean convergent boundary, there will be a formation of volcanoes.
What are three major islands arcs?
Island arcs are also called oceanic arcs. Many volcanoes form near converging plate boundaries where subduction occurs. Subduction causes slabs of oceanic crust to sink beneath a deep-ocean trench into the mantle. The crust melts and forms magma, which then rises back toward the surface. Volcanoes form when the magma erupts as lava. At the boundary where two oceanic plates collide, volcanoes can create a string of islands called an island arc. There are many island arcs. The main ones that we read of most often include Japan, New Zealand, Indonesia, Caribbean Islands, Philippines, and the Aleutians.
