27. < BackNext >PreviewMain Chapter 11 CRCT Preparation 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.

29. < BackNext >PreviewMain Chapter 11 CRCT Preparation 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.
