Answer:
Continental volcanic arcs are associated with the oceanic-continental convergent plate boundary.
Explanation:
Where two structural plates combine, on the off chance that either of the plates is maritime lithosphere, a subduction zone will form.When the level of magma increases above this zone it leads to the formation of volcanic arc. The volcanic arc is named so due to its appearance chains of volcanoes in arc shape.
Based upon the types of plates colliding it leads to the formation of two types of volcanic arc. When collision occurs between two oceanic plate it leads to the formation of volcanic arc, whereas when collision occurs between ocenain plate and Continental plate, it leads to the formation of continental volcanic arcs.
Answer:
Option (1)
Explanation:
When an oceanic plate and a continent plate shares a convergent plate boundary with each other, it leads to the subduction of the oceanic plate as the oceanic plate is denser than the continental plate. Due to this plate subduction, the subducting plate melts at great depth that allows the magma to rise up towards the surface in the over-riding plate in the form of volcanoes. It also forms continental volcanic arcs and generates deep focus earthquakes.
Thus, the correct answer is option (1).
