Groundwater

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

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.

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

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

Which of the following are wells used for? CHOOSE ALL THAT APPLY!

• Wells are used to determine the height of the water table.
