13. How might the water level of an aquifer affect water wells that are drilled into the aquifer? How can the wells affect the water level of an aquifer?



13. Answer - Full credit answers should include the following points:

• If a well is not deep enough, it will dry up when the water table falls below the bottom of the well.

• If an area has too many wells, groundwater can be removed rapidly.

• If groundwater is removed too rapidly, the water table will drop and all of the wells will run dry.



14. There are more than 500 caves in Georgia, many of them in the far northwestern counties of Dade and Walker. How do caves form in existing layers of limestone?



14. Answer - Full credit answers should include the following points:

• Limestone is permeable, so water can seep through it.

• Caves are formed in limestone by weak acids in circulating groundwater.

• Over time, the acidic water erodes caves from tiny cracks in the limestone.
