which describes an underground layer of porous and permeable rock that holds water

Answer 1

The underground layer of porous and permeable rock that holds water is known as an aquifer. Aquifers are crucial for storing groundwater, which can be tapped into for drinking water, irrigation, and various industrial purposes. They consist of materials like sand, gravel, or porous rock formations that allow water to flow through them, enabling the collection and movement of groundwater.
