Below are sample questions representative of the exercises included on this worksheet and related 9.104 Convergent Boundaries and Mountain Building skill assessments:

Problem 1Difficulty: Mastery

Which synthesis best explains how ocean-continent convergence can produce trenches, earthquakes, volcanic mountains, and folded mountains in one region?

AA transform fault creates deep earthquakes, a mantle wedge, a volcanic arc, and compression without convergence.

BTwo plates move apart to form a trench, stop earthquakes, melt the continent, and unfold the mountains.

CA dense oceanic plate subducts to form a trench and earthquake zone, while slab fluids feed arc magma and compression folds the overriding plate.

DErosion alone carves all trenches and mountains while plates remain fixed.

Solution & Explanation:Ocean-continent convergence is a connected system: subduction forms the trench and earthquake pattern, while melting and compression build mountains.

Problem 2Difficulty: Mastery

A cross-section of a mountain belt uses a vertical scale much larger than its horizontal scale. Which limitation should students remember?

AEvery label must be wrong if a scale is exaggerated.

BThe diagram cannot show any real relationships between plate motion and mountains.

CThe steepness and thicknesses may be exaggerated, so the diagram should not be read as perfectly to scale.

DVertical exaggeration means subduction does not happen in nature.

Solution & Explanation:Cross sections can clarify relationships but often exaggerate vertical dimensions, so students should use labels and scale information carefully.

Problem 3Difficulty: Mastery

Which evidence would best distinguish an ancient subduction margin from an ancient transform fault zone?

AA single straight valley with only horizontal offset and no arc rocks

BLoose beach sand deposited by waves during a storm

CSymmetric magnetic stripes centered on a ridge axis

DArc volcanic rocks, accretionary-wedge sediments, and high-pressure metamorphic rocks

Solution & Explanation:Ancient subduction can leave arc magmatism, accreted sediments, and high-pressure metamorphism; transform zones mainly record lateral motion.
