Subduction of oceanic lithosphere under a continental block gives rise to what type of geologic structure that is characterized by a continental volcanic arc and associated igneous plutons?
The subduction of oceanic lithosphere under a continent forms a volcanic arc on the continental margin. This arc is characterized by intense volcanic activity producing a chain of stratovolcanoes and igneous plutons intruding into the continental crust.
Match the mountains with the type of collision that formed them?
Andes - continental oceanic aleutians - oceanic oceanic North American cordillera - arc continent Appalachians - continental continental
What is continental volcanic arc?
A continental volcanic arc is a chain of volcanoes that forms on a continental plate where two tectonic plates converge. The subduction of an oceanic plate beneath a continental plate results in magma generation and volcanic activity along the continental margin. These volcanic arcs are associated with earthquakes, volcanism, and mountain building.
What are the steps in arc-continental mountain formation?
Subduction of oceanic plate beneath continental plate causes melting and magma formation. Magma rises towards the surface, creating volcanic activity and forming arc-shaped mountain ranges. Sedimentary rocks are uplifted and folded due to tectonic forces, contributing to the growth of the mountain range. Erosion and weathering continue to shape the mountains over time.
When converging two continental plates is it possible to form a volcano?
Yes, when two continental plates converge, they can create a subduction zone where one plate is forced under the other, leading to the melting of rock and the formation of magma. This magma can rise to the surface, leading to the formation of a volcanic arc and volcanoes.
What is the continental volcanic arc?
Volcanic arc along continental boundaries. Example would be the "ring of fire" which surrounds the pacific ocean along continental plates.
Which feature can be produced at an ocean-continental convergence?
Parallel belts of folded mountains and volcanic mountains
Which can be produced at an ocean-continental convergent boundary?
continental volcanic arc
Which feature can be produced at an ocean continental convergence?
continental volcanic arc. :)
Is Mount rainier an Island Arc?
No. Mount Rainier is on the mainland, so it is part of a continental arc.

What is a continental arc system?
These arc systems form at collision plate margins where an oceanic plate is being subducted under a continental plate. As the oceanic plate melts, the magma rises and finds cracks in the continental plate above and creates volcanoes. These volcanoes occur all the way along this plate margin. For example the cascade volcanic arc on the north west coast of USA.
Match the mountains with the type of collision that formed them?
Andes - continental oceanic aleutians - oceanic oceanic North American cordillera - arc continent Appalachians - continental continental
What plates can create a volcanic arc?
An oceanic plate being subducted under a continental plate.
What plates create a volcanic arc?
An oceanic plate being subducted under a continental plate.
Is redoubt volcano an island arc?
No, Redoubt Volcano is not part of an island arc. It is located in the Aleutian Range in Alaska and is associated with the Aleutian volcanic arc, which is a chain of volcanoes formed by the subduction of the Pacific Plate beneath the North American Plate.
