Detailed explanation-1: -Groundwater is stored in aquifers, which are spaces below ground in which water is trapped within layers of sand and gravel. The water stored in aquifers originates as rain and snowmelt that flows downward from the surface through the different layers of soil.

Detailed explanation-2: -An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers: confined and unconfined.
