Question

which statement best describes the illustration? a mountain forms at a transform boundary. a mountain forms at a divergent boundary. a volcano forms at an oceanic - oceanic convergence boundary. a trench forms at continental - continental convergence boundary.

Explanation:

• Transform boundaries are where plates slide past each other, and mountains don't form here.
• Divergent boundaries are where plates move apart, and mountains don't form in the typical sense shown in the illustration (volcanic activity at divergent is more like mid - ocean ridges).
• Continental - continental convergence forms mountains (not trenches).
• At an oceanic - oceanic convergence boundary, one plate subducts, and magma rises to form volcanoes as shown in the illustration.

Answer:

C. A volcano forms at an oceanic - oceanic convergence boundary.
