GEOLOGY 105 LAB FINAL EXAM| 100+ ACTUAL
QUESTIONS & CORRECT VERIFIED ANSWERS ||
GRADED A+
1. natural selection ANS << organisms better adapted to their environment tend to
survive and produce more offspring
-main process that brings about evolution
2. why is evolution predictable in the short term, but not the long term,
according to the grants? ANS << In the long term, evolution is unpredictable
because environments change unpredictably and environment determine the
directions a species will evolve and to what degree
3. normal fault ANS << divergent plate
boundary hanging wall moves down
tensional forces pulling away
4. reverse fault ANS << convergent plate
1/3
,boundary hanging wall moves up
tensional forces going towards eachother
5. right lateral strike-slip ANS << right side
moves down horizontal motion
6. left lateral strike-slip ANS << transform
bounday left side moves down
7. anticline ANS << folding where the oldest layer is in the
center would see at a dorm
n shape
8. syncline ANS << folding where youngest layer is in the
center would see at a basin
u shape
9. law of original horizontality ANS << sedimentary rock layers are deposited
horizontal- ly..like a cake
if they're no longer flat --> faulting or folding occured
10. law of later continuity ANS << lava flows and strata extended laterally in all
directions until they thin out
11. law of superposition ANS << if rocks are undisturbed the oldest layer will be
on the bottom of the sequence and the youngest will be on the top
12. law of cross-cutting ANS << a feature (fault) that cuts across a sequence and
therefore is younger than the sequence it cuts through
13. law of unconformity ANS << a surface that represents gaps in the geologic
2/3
, record are due to erosion or non-deposition
14. disconformity ANS << beds below unconformity are parallel, erosion
15. angular unconformity ANS << rocks tilted, then eroded
16. nonconformity ANS << sedimentary rocks rest on eroded surface of non-
sedimentary rocks
3/3
