Which term describes groundwater stored in porous rocks?

• A. Lakes
• B. Wells
• C. Reservoirs
• D. Aquifers

Answer: (D)

Groundwater stored in the pore spaces of porous rocks is described as an aquifer. An aquifer is a permeable layer of rock or sediment that holds groundwater in its pores and can transmit it, allowing water to move and be extracted by wells or discharged at springs. Porosity provides the storage space, while permeability enables the flow. Lakes are surface water bodies, wells are points where groundwater is accessed, and reservoirs are storages of surface water (or man-made water bodies), so the term that best describes groundwater stored in porous rocks is aquifer.
