Porous rock which stores water is called?

Explanation:
An aquifer is a porous, permeable rock layer that stores groundwater and allows it to move so it can be drawn up by wells. The storage comes from porosity (the spaces in the rock) and the flow comes from permeability (the connected pathways between those spaces). If a layer is too impermeable, water can’t move through it, so it doesn’t act as an aquifer. A reservoir is just a general term for storage of water, not a specific rock feature, and sandstone is a rock type that can form an aquifer if it has enough interconnected pores and permeability.
