Question

Quizplus · Accepted Answer

Island arcs are typically composed of volcanic and sedimentary rocks that are created at subduction zones. When they collide with a continent, they become accreted terranes, which are pieces of the crust that have been added to a continent through tectonic processes. Over time, these accreted terranes can contribute to the growth and evolution of a continent.
