What forms at a subduction zone?
Volcanic arcs and oceanic trenches commonly form at subduction zones.
Where can a shield volcano be found?
It can be found along subduction-related volcanic arcs or all by themselves
Do volcanic eruptions only cause destruction?
No. Volcanic eruptions can build mountains and form new land. Many occur in remote areas where there is not much to destroy.
What kind of mountains form from hot spots?
Hot spot volcanos. As these age they can become island chains and eventually subsurface seamount arcs if the hot spot is in the ocean.
What is the construcion tool for drawing arcs?
A compass is mainly used to draw perfect circles, but it can also be used to draw arcs of different sizes.
What is the differences between volcanic island arcs and volcanic arcs?
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
What does an oceanic-oceanic convergence give rise to?
volcanic island arcs

What forms at a subduction zone?
Volcanic arcs and oceanic trenches commonly form at subduction zones.
Is a volcanic arc the same thing as a volcanic mountain range?
Volcanic arcs are usually island arcs off the coast of a continent, while volcanic mountain ranges are usually inland inside a continent. But the volcanoes of a volcanic island arc do form an undersea volcanic mountain range. So to some extent the difference is mostly a matter of terminology.
What does an oceanic-oceanic convergence rise to?
volcanic island arcs
What results from a convergent boundary?
Continental mountains, ocean trenches, volcanic mountains, volcanic islands and arcs.
What causes volcanic islands arcs to form?
Volcanic arcs are formed as a more dense oceanic plate collides with a less dense oceanic plate, subducts, and creates molten material which rises through the overriding plate, which in turn creates submarine volcanoes. The volcanoes may grow until they eventually breach the surface of the water, producing volcanic arc landmasses.
What forms when oceanic plates collide?
1. Oceanic trenches. 2. Volcanic islands. 3. Volcanic mountains. and 4. Volcanic arcs.
Which geologic regions creates volcanic arcs?
convergent plate boundaries
What does ocean ocean convergence produce?
mainly continental volcanic arcs
What do oceanic vs oceanic convergence produce?
volcanic island arcs
