- 1. Multiple Choice
What is the best definition of a water table?
The level to which a river rises when it floods
The boundary between the land and the ocean
The top of the saturated zone in an aquifer
The bottom of the saturated zone in an aquifer
The top of the unsaturated zone in an aquifer
- 2. Multiple Choice
What would cause the water table to lower?
High rates of evaporation and transpiration
Low rates of evaporation and transpiration
Increasing amounts of runoff
A heavy rainstorm with a lot of precipitation
- 3. Multiple Choice
What is infiltration?
The process by which water sinks into the ground
The zone where there are still air spaces left between the particles.
The process by which water vapor turns into liquid water and forms fog or clouds.
The process by which water does not sink into the ground, but rather travels along the surface.
- 4. Multiple Choice

sand (0.02 cm)
silt (0.002 cm)
clay (0.0002 cm)
- 7. Multiple Choice
Which soil would have the greatest capillarity?
sand (0.02 cm)
silt (0.002 cm)
clay (0.0002 cm)
- 8. Multiple Choice
What is capillarity?
When water cannot infiltrate a substance
Water being held onto by rock or sediment
The ability of water to move upward against gravity in a material
The percentage of empty space in a material
- 9. Multiple Choice
These containers have the same volume of beads which are representing soil particles. What is the relative porosity and permeability of each?
The container on the left has the higher permeability and porosity
The container on the right has the higher permeability and porosity
The container on the left has the higher permeability, but they both have the same porosity
The container on the right has the higher permeability, but they both have the same porosity
- 10. Multiple Choice
500 mL of water is added to each tube and allowed to drain out. Which container would have the highest retention of water after it drained? (particle size gets bigger as you move to the right)
A
B
C
D
They would all be the same in terms of retention
- 11. Multiple Choice
How would the porosity of the poorly sorted sediment compare to the well sorted sediment?
It would be greater in the poorly sorted sediment
It would be less in the poorly sorted sediment
It would be the same in both
- 12. Multiple Choice
How does the porosity of frozen soil compare with unfrozen soil?
It is less in the frozen soil
It is greater in the frozen soil
The porosity of both would be the same
- 13. Multiple Choice
