Q: What is formed when a subducting plate flows under another tectonic plate?


Read this paragraph and choose the correct option from the provided answers:

As you would expect, where plates collide there are lots of intense earthquakes and volcanic eruptions. The subducting oceanic plate melts as it reenters the mantle. The magma rises and erupts. This creates a volcanic mountain range near the coast of the continent. This range is called a volcanic arc . The Andes Mountains, along the western edge of South America, are a volcanic arc ( Figure below ).

 Choices:

- magma

- boundary plate

- fault line

- volcanic arc


A:
volcanic arc
