Below are sample questions representative of the exercises included on this worksheet and related 9.79 Seismic Waves and Earth's Interior skill assessments:

Problem 1Difficulty: Mastery

Which explanation best integrates the wave standard and Earth-systems standard for this skill?

ADifferent seismic waves reveal material properties and layer interactions inside Earth's system.

BOnly surface damage matters when studying Earth's interior.

CEarth's layers can be mapped without evidence from waves or materials.

DSeismic waves are unrelated to Earth's structure once an earthquake ends.

Solution & Explanation:The skill connects wave behavior with systems reasoning: waves interact with materials, and those interactions reveal interior structure.

Problem 2Difficulty: Mastery

Which research plan would best improve confidence in an Earth interior model based on seismic waves?

AUse calibrated stations worldwide, compare many events, and test whether predicted arrivals match records.

BChoose only records that fit the first model and discard the rest.

CUse one uncalibrated station and ignore missing waves.

DMeasure surface shaking without time stamps or locations.

Solution & Explanation:Reliable models require calibrated data, many paths, and comparison between predictions and observations.

Problem 3Difficulty: Mastery

How can records from small instruments at Earth's surface provide evidence about the deep core?

ASeismic waves travel through the Earth system, so surface records contain path information from deep layers.

BDeep layers have no effect on waves reaching the surface.

CSurface records are direct photographs of core minerals.

DThe instruments drill tiny holes to the center during each earthquake.

Solution & Explanation:The timing and paths of body waves are affected by deep layers before the waves reach surface stations.
