GEOLOGY

Detailed explanation-1: -Groundwater. Groundwater is water that has infiltrated the ground to fill the spaces between sediments and cracks in rock. Groundwater is fed by precipitation and can resurface to replenish streams, rivers, and lakes.

Detailed explanation-2: -Groundwater is the water found underground in the cracks and spaces in soil, sand, and rock. It is held in aquifers-permeable water-bearing rock and/or sediment-and can be extracted through wells or bubbles up naturally through a spring or is discharged into lakes or streams.

Detailed explanation-3: -Groundwater is found in two zones. The unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores. The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone.

Detailed explanation-4: -Groundwater exists and flows within the small spaces between soil particles and fractured rock. The area where water fills these spaces is called the saturated zone.

Detailed explanation-5: -Groundwater is water that exists underground in saturated zones beneath the land surface. The upper surface of the saturated zone is called the water table.
