Question

Quizplus · Accepted Answer

Accretion is the process by which terranes, which are fragments of crustal material, are added to a continent or landmass. This process typically occurs at convergent plate boundaries where one tectonic plate may carry an island arc or other crustal fragment toward another plate, eventually adding the terrane to the larger landmass as they collide and merge.
