Which term describes water stored within rocks underground?

• A. Groundwater storage
• B. Groundwater flow
• C. Surface runoff
• D. Infiltration

Answer: (A)

Water stored underground in the pores and fractures of rocks and soils forms groundwater, which acts as a subterranean reservoir. The term that describes this kept-up quantity is groundwater storage, the amount of water held in the saturated subsurface, often in aquifers. The other ideas describe movement or entry rather than storage: groundwater flow is the movement of water through the underground rock, surface runoff is water that travels over the land surface, and infiltration is water seeping from the surface into the soil to begin recharging groundwater.
