Question

an underground formation that contains groundwater that is usually tapped into by wells

Answer 1

An underground formation that contains groundwater, which is typically accessed through wells, is known as an **aquifer**. Aquifers are geological formations that can store and transmit water, allowing it to be extracted for various uses, including drinking water, irrigation, and industrial processes. They are essential components of the hydrological cycle and can be composed of various materials such as sand, gravel, rock, or limestone, which facilitate the movement of water through the subsurface.
