Below are sample questions representative of the exercises included on this worksheet and related 9.96 Relative Dating and Superposition skill assessments:

Problem 1Difficulty: Mastery

Using the diagram of rock layers, pluton P cuts layers R and S but not layer T. Pluton P also contains inclusions from layer R. Which interpretation correctly combines the evidence?

APluton P is older than R, S, and T.

BLayer T is older than pluton P because P does not cut it.

CLayers R and S are older than pluton P, and pluton P is older than layer T.

DLayer R is younger than P because pieces of R are inside P.

Solution & Explanation:P cuts R and S, so P is younger than those layers. Inclusions from R also make R older than P. Since P does not cut T, T was deposited after P.

Problem 2Difficulty: Mastery

Refer to the rock-layer diagram: Layers A, B, and C are cut by dike X. Fault F offsets dike X and the layers. Erosion surface U truncates the fault, and layer D rests on U. Which sequence is oldest to youngest?

AA, B, C, dike X, fault F, erosion U, D

BA, B, C, dike X, erosion U, D, fault F

CD, erosion U, fault F, dike X, C, B, A

DA, B, C, fault F, dike X, erosion U, D

Solution & Explanation:X cuts A-C, so it came after them. F offsets X, so F is younger than X. U truncates F, and D was deposited on U.

Problem 3Difficulty: Mastery

Based on the rock-layer diagram, basal conglomerate Y above an unconformity contains angular fragments of dike X, but dike X does not cut Y. Which order is best supported?

ADike X intruded, erosion formed the unconformity, conglomerate Y was deposited

BDike X intruded after Y because fragments are inside Y

CConglomerate Y was deposited, dike X intruded, erosion formed the unconformity

DErosion formed the unconformity, conglomerate Y was deposited, dike X intruded

Solution & Explanation:Fragments of X inside Y show X is older than Y. The unconformity records erosion that exposed and cut X before Y was deposited.
