In a limestone region, rainwater and rivers quickly disappear underground, but the porous rock also stores this water below the surface, giving a reliable supply from boreholes and wells. What is the name of this underground water-storage feature?

Model answer

aquifer

Also accepted: aquifers

Explanation

Limestone's porosity lets water percolate down and collect underground in aquifers, which can then be tapped by boreholes and wells.
