Groundwater

What does the quantity of groundwater that can be stored depend upon?

• It depends upon the porosity of the underground rock.

• It depends upon the pH of the groundwater.

• It depends upon the underground depth of the storage system.

• It depends upon the temperature of the underground rock.

A place where the water table intersects the ground surface and where a natural flow of groundwater results is called:

• a spring.

• a geyser.

• an aquatard.

• a fissure.

What is the most common method for removing groundwater?

• a well bored into the zone of saturation

• accessing the water table by use of low-grade explosives

• building a water tower

• damming up a river

Geologically, groundwater is important as an agent of:

• erosion

• deposition

• lithification

• subduction

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 top of the unsaturated zone in an aquifer

What would cause the water table to lower?

• Periods of low precipitation

• Low rates of evaporation and transpiration

• Increasing amounts of runoff

• A heavy rainstorm with a lot of precipitation

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.

Which surface would have the most runoff from it after a rainstorm?

• 
• 
• 
• 

Which surface would be impermeable?

• 
• 
• 
• 

Water is able to flow more easily through the aquifer because its material has a ___________.

• low permeability

• low porosity

• high porosity

• high permeability
