A)More water is taken out of the aquifer than is gained from recharge.
B)Less water is taken out of the aquifer than is gained from recharge.
C)Springs and rivers take out more water than does pumping.
D)As the aquifer dewaters,it expands,increasing the amount of pore space in which to store water.

Quizplus · Accepted Answer

The graph shows that the blue line, representing groundwater pumping, is consistently above the red line, representing recharge from precipitation. This indicates that more water is being taken out of the aquifer than is being gained from recharge, leading to a declining water level. Choice B is therefore incorrect. The graph does not provide information on the balance between pumping and natural outflows such as springs and rivers, so choice C is also incorrect. Choice D is an incorrect statement about the behavior of a depleted aquifer.
