Exam Review Game

Exam 3

• There will be 9 rounds in the game:

• 5 multiple choice rounds

• 4 drawing rounds

• Participation in the activity is worth 8/8 stamps and

the winning team gets 9/8 stamps.

Multiple Choice Round Rules

• (^) You have 1 minute for every person to silently answer all the multiple

choice questions on the screen.

• You will then have 1 minute to discuss as a group and mark your

answers on your team scorecard.

• (^) Every team that answers all of the questions correctly will be

awarded a point for the round.

MC Round 2:

1. Just like the moment magnitude scale, the Richter scale is

logarithmic. Each step in the Richter scale is equal to a 10x increase

in the amplitude of a seismogram. How much larger, therefore, is the

amplitude from a M6 earthquake than a M3 earthquake?

a. Twice as large b. 30 times as large c. 90 times as large d. 1000 times as large

2. Foliation occurs due to ________________.

a. pressure resulting from burial under younger sedimentary rocks. b. deposition of sediment by gravity c. alignment of minerals under differential pressure d. alignment of minerals under lithostatic (confining) pressure

3. What is the strike and dip measurement that is depicted by the

symbol?

a. N 60 E, 45° SE b. N 45 E, 60° SE c. N 45 W, 60° SE d. N 60 E, 60° SW

MC Round 3:

1. What type of fault is fault B (In the cross section above)?

a. Normal b. Reverse c. Strike Slip d. Thrust

2. In the cross section above, what is the relationship between the black lava flow and

Fault C?

a. The lava flow is younger than the fault b. The lava flow is older than the fault c. The lava flow is the same age as the fault d. There is not enough information to determine the relative ages of the two.

3. Which principle of relative dating did you use to determine your answer to the

previous question?

a. Law of Original Horizontality b. Law of Superposition c. Law of Cross Cutting Relationships d. Law of Fossil Succession

MC Round 5:

1. You observe some sedimentary rocks near Horsetooth Reservoir

that are striking roughly north-south and have a dip of 20° to the

east. You infer that _________.

a. Tectonic forces have caused the rocks to tilt. b. The rocks were deposited at an angle, as the interior seaway collided with the Ancestral Rockies. c. The force of gravity alone has caused the rocks to tilt. d. The construction of the reservoir caused the rocks to tilt.

2. Which principle did you use to answer the question above?

a. The principle of Original Horizontality b. The principle of Superposition c. The principle of Cross Cutting Relationships d. The principle of Fossil Succession

3. What type of fold is shown in the map below?

a. Anticline b. Syncline c. Monocline d. No fold is present

Drawing Round Rules

• (^) Each team will be assigned an area of white board.
• (^) One person from each team will be the scribe and they will be the

only one allowed to use the Expo pen.

• (^) Each round must have a new scribe.
• (^) The scribe will have 2 minutes to draw their picture. Others in the

groups may help direct the scribe, but may not operate the Expo pen.

• (^) You may not consult your notes.
• (^) 1 point for each round will be awarded to the team with the best

drawing as judged by Emily.

Drawing Round 2:

• Draw a cross section of a reverse fault. Label the

Hanging Wall and Foot Wall and include half arrows.

Drawing Round 3:

• Draw an angular unconformity

Special Tie Breaker Round

• Draw a schematic cross section view across the

Rocky Mountains along the A to A’ transect below.

Make sure your cross section shows the orientation

of the strata (sedimentary layers) in the Front Range.
