Define volcanic island arc.
Understand the Problem
The question is asking for a definition of a volcanic island arc, which refers to a type of landform that is formed through volcanic activity, typically associated with the subduction of tectonic plates. The focus will be on explaining the characteristics and formation of these geological features.
Answer
Volcanic island arcs are curved chains of volcanic islands formed above a subducting oceanic tectonic plate.
Volcanic island arcs are long, typically curved chains of volcanic islands formed on the basin margins above a subducting oceanic tectonic plate.
