Water held in rocks underground is known as which term?

• A. Groundwater flow
• B. Groundwater storage
• C. Infiltration
• D. Evaporation

Answer: (B)

Water trapped in the pores and fractures of rocks beneath the surface is groundwater. The term that best matches “water held” underground is groundwater storage, because it describes how much of that groundwater is stored in underground formations at a given time. Groundwater flow refers to movement through the subsurface, infiltration is water entering the ground from the surface, and evaporation is water lost to the atmosphere.
