What else can I help you with?
What geologic features are associated with each type of convergent boundary?
Subduction zones, trenches and volcanic islands: the boundary that is oceanic. Trenches and volcanic islands: an oceanic-continental boundary. Folded mountain ranges: a continental and continental collision.
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.
If a plate of ocean crust plunged underneath a continental platewhat landforms do you expect to develop?
When ocean crust subducts beneath a continental plate, landforms such as deep ocean trenches, volcanic arcs, and mountains can develop. This process can also lead to the formation of earthquakes and volcanic activity due to the intense geologic activity at the subduction zone. Over time, the subduction process can result in the creation of island arcs or continental volcanic belts.
When an oceanic plate is pushed under a continental plate resulting in volcanic activity this type of boundary forms?
A subduction zone is formed when an oceanic plate is pushed under a continental plate, resulting in volcanic activity. Oceanic crust is denser and sinks beneath the less dense continental crust, leading to the formation of volcanic arcs on the overriding plate.
What forms on the ocean floors in a subduction zone?
Deep ocean trenches and volcanic arcs form on the ocean floors in a subduction zone. The oceanic plate is forced beneath the continental plate, creating a deep trench. Melting of the subducted plate leads to the formation of magma, which can erupt at the surface to create volcanic arcs.
What is the type of rock typical of island arcs?
The type of rock typical of island arcs is andesite. Andesite is an intermediate volcanic rock that is commonly found in volcanic arcs where oceanic crust subducts beneath continental crust, forming magma that eventually erupts to create volcanic islands.
How are volcanic arcs and island arcs simalr?
Volcanic arcs and island arcs are both formed as a result of subduction zones, where one tectonic plate is forced beneath another. In both cases, the subduction process leads to the melting of the mantle and the formation of magma, which rises to create volcanic activity. Volcanic arcs typically occur on continental margins, while island arcs are found in oceanic settings, often resulting in a chain of volcanic islands. Despite this geographical distinction, both arcs share similar geological processes and are characterized by volcanic activity and associated tectonic features.
What geologic features are associated with each type of convergent boundary?
Subduction zones, trenches and volcanic islands: the boundary that is oceanic. Trenches and volcanic islands: an oceanic-continental boundary. Folded mountain ranges: a continental and continental collision.
Newly formed land consisting of an arc-shaped island chain is called?
Continental volcanic arcs
Where can a shield volcano be found?
It can be found along subduction-related volcanic arcs or all by themselves
Subduction of oceanic crust at a continental margin creates .?
Ocean trenches and Island arcs.
What are the three different setting of convergent boundaries?
Oceanic-continental: Oceanic plate is subducted beneath continental plate, creating volcanic arcs and mountain ranges. Oceanic-oceanic: One oceanic plate is subducted beneath another, forming deep ocean trenches and volcanic island arcs. Continental-continental: Collision of two continental plates, leading to intense folding and faulting, creating high mountain ranges.
What types of mountains form when oceanic plates collide and slide under continental plates?
When oceanic plates collide and slide under continental plates, they can form volcanic mountain ranges called continental volcanic arcs. These arcs result from the melting of the descending oceanic plate, which then feeds magma to the Earth's surface. Examples include the Andes in South America and the Cascades in North America.
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.

When ocean crust subducts beneath a continental plate, landforms such as deep ocean trenches, volcanic arcs, and mountains can develop. This process can also lead to the formation of earthquakes and volcanic activity due to the intense geologic activity at the subduction zone. Over time, the subduction process can result in the creation of island arcs or continental volcanic belts.
Which boundaries are likely to result in volcanic island arcs?
Volcanic island arcs are likely to result from convergent boundaries where an oceanic plate subducts beneath another oceanic plate or a continental plate. The subducted plate can melt, causing magma to rise and form a series of volcanic islands above the subduction zone.
When an oceanic plate is pushed under a continental plate resulting in volcanic activity this type of boundary forms?
A subduction zone is formed when an oceanic plate is pushed under a continental plate, resulting in volcanic activity. Oceanic crust is denser and sinks beneath the less dense continental crust, leading to the formation of volcanic arcs on the overriding plate.
