If subduction occurs beneath the continental crust a(n) _____________ is formed. If subduction occurs beneath the oceanic lithos
phere, a(n) __________ is formed. A) island arc, volcanic arc B) volcanic arc, island arc C) transform fault, transform arc D) transform arc, transform fault
The first one would be island arc as subduction occurs beneath the continental crust. When it occurs, the compressional force placed upon the continential plate will cause the rock to bend and arc up form a series of volcanoes leading to the formation of volcanic arc.
The second one would be island arc as subduction occurs beneath the oceanic lithosphere. When subduction forced the crust to bend, rocks are compressed and arc up, forming a series of island, the formation of island arc then occurs.
C and D is incorrect as no transformation has take place.
