Part 1: Looking at Diagrams (5 pts per question)
Directions: Look at the diagram and answer the question.
What is Figure 1&2 demonstrating?
Note that there are multiple answers to this problem.
Figure 1
Light Blue: High hydraulic-conductivity aquifer
Dark Blue: Low hydraulic-conductivity confining layer
Grey: Very low hydraulic-conductivity bedrock
Arrows: Indicates direction of groundwater flow
Figure 2
Answer: Acceptable Answers:
 Direction of groundwater flow
 A map of groundwater flow
 A diagram of how underground aquifers work
 Parts, layers, etc of an underground aquifer
 Anything else that is reasonable for the diagrams or relate to above answers.
2. What is the relationship between the stream and the unconfined aquifer in figure 1&2?
A. water is moving from the stream into the aquifer
B. water is moving from the aquifer into the stream
C. there is no relationship between the stream and the unconfined aquifer
D. None of these answers are possible based upon information provided
3. Which of the following would be the most likely type of material in the confining (the grey) layer in
figure 1?
A. sandstone
B. gravel
C. granite
D. topsoil
4. In figure 1&2, which body of water would probably have the highest rate of flow?
A. groundwater in the unconfined aquifer B. surface water in the stream
C. confining layer D. None of the above; they have equal flow rates
Figure 3
5. Look at figure 3. What type of rock makes up the “Groundwater flow” section (the pale, grey blue
section)? There may be more than one correct answer. Pick one of them. This isn’t a trick question.
A. basalt
B. gravel
C. granite
D. topsoil
E. none of the above
6. True/False Material that allows water to penetrate and flow through it is considered
“tolerate” and “porous.”
Part 2: Multiple Choice (1 pt per question)
7. The zone immediately below the land surface where the pores and fractures contain both
water and air is the:
A. confining zone B. withdrawal zone
C. unsaturated zone D. saturated zone
------------------------------------------------------------------8. An outflow of water from a stream, pipe, groundwater aquifer, or watershed is called:
A. recharge B. dismiss
C. discharge D. ejection
------------------------------------------------------------------9. The flow of water from the land surface into the subsurface is:
A. permeation B. admission
C. penetration D. infiltration
------------------------------------------------------------------10. The solid rock beneath the soil and superficial rock is:
A. foundation B. core rock
C. bedrock D. base
------------------------------------------------------------------11. An aquifer containing groundwater that has an impermeable layer below but not above it is
called a(n):
A. unconfined aquifer B. confined aquifer
C. restricted aquifer D. upper aquifer
