RELATIVE DATING PRACTICE


Use the illustration to mark the correct answer.



The oldest rock shown is (A, B, G, I, U).
The structure at B is a(n) (anticline, syncline, sill, horizontal bedrock, laccolith).
The structure at J is a(n) (anticline, syncline, sill, horizontal bedrock, laccolith).
The youngest of the following is (A, B, G, J, I).
The youngest rock is (A, B, I, R, T).

The second youngest rock is (A, I, P, R, T).
The youngest sedimentary rock is (B, J, R. S, T).
G is a(n) (laccolith, dike, sill, stock, batholith).
R is a(n) (dike, sill, stock, lava flow, laccolith).
S is (older than, younger than, the same age as) Q.

S is (older than, younger than, the same age as) R.
A is a(n) (laccolith, dike, sill, stock, lava flow, laccolith).
N is a(n) (dike, sill, stock, lava flow, laccolith).
M is the same age as (M, N, O, P, Q).
K is a(n) (dike, sill, anticline, unconformity, fault).

K occurred before (D, F, J, folding, L).
The NEXT event represented after folding is (faulting, erosion, L, A, I).
The rock at M is (quartzite, sandstone, marble, slate, NONE of these).
The rock at Q is (quartzite, sandstone, marble, slate, NONE of these).
The rock at S is (quartzite, sandstone, marble, slate, NONE of these).

R is (older than, younger than, the same age as) T.


Answers:

B, anticline, syncline, I, I;
R, T, dike, sill, the same age as;
the same age as, dike, lava flow, N, unconformity;
L, erosion, quartzite, marble, slate;
younger than.
