Below are sample questions representative of the exercises included on this worksheet and related 8.119 Locate Plate Boundaries from Seismic Maps skill assessments:

Problem 1Difficulty: Mastery

Which final conclusion best uses both earthquake and volcano distributions to infer plate boundary location and type?

AVolcanoes alone always locate every boundary exactly

BEarthquakes should be ignored if any volcanoes appear

COnly coastlines and country borders are needed to map plates

DA continuous seismic belt locates the boundary, and volcano patterns plus earthquake depths help identify whether it is divergent, transform, or convergent

Solution & Explanation:The strongest interpretation combines where earthquakes cluster with volcano patterns and depth data to locate and classify plate boundaries.

Problem 2Difficulty: Mastery

Use the map to decide which student explanation is best. Student A says the boundary follows the earthquake belt. Student B says it follows the nearest river. Student C says it follows the map border. Student D says it follows a single volcano symbol.

AStudent B, because rivers always mark plate edges

BStudent C, because map borders are scientific data

CStudent A, because earthquake belts are direct tectonic evidence

DStudent D, because one volcano is enough to define a boundary

Solution & Explanation:Earthquake belts are direct evidence of active plate interaction; rivers, map borders, and isolated symbols are weaker or unrelated.

Problem 3Difficulty: Mastery

A boundary has earthquakes that are shallow at the trench, intermediate under the volcano arc, and deep beyond the arc. Which statement best explains the pattern?

AThe earthquakes trace a slab that continues sinking beneath the overriding plate

BThe plate boundary is a mid-ocean ridge with new seafloor

CThe volcano arc is unrelated because earthquakes are present

DAll earthquakes at boundaries must have the same depth

Solution & Explanation:The sequence from shallow to deep earthquakes traces the path of a subducting slab beneath the overriding plate.
