an aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials. groundwater can be extracted using a water well. the study of water flow in aquifers and the characterization of aquifers is called hydro-geology.
below is an image of an aquifer:
the parts of the image that are circled and show cracks of water are called aquifers. hope this !
electricity is a term used to describe the energy produced when electrons are caused to directional flow from atom to atom. this movement of electrons between atoms is called electrical current.
