Question

Quizplus · Accepted Answer

When two oceanic plates converge, one plate is usually forced below the other into the mantle where it melts, forming magma. This magma can rise to the surface, erupting to form volcanoes. Over time, these volcanoes can emerge above the sea level, forming a curved chain of islands known as an island arc.
