GEOLOGY

Detailed explanation-1: -The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table (Diagram 1).

Detailed explanation-2: -The upper limit of the saturated zone may be thought of as the water table (it is shown as a dashed line on the diagram below). The zone above the water table, where pore spaces contain both air and water, is known as the unsaturated zone.

Detailed explanation-3: -Groundwater is the saturated zone of soil/rock below the land surface | U.S. Geological Survey. An official website of the United States government.

Detailed explanation-4: -This zone, where all the pores are completely filled with water, is known as the zone of saturation. The uppermost portion of the zone of saturation is known as the water table or the phreatic surface. It forms the dividing line between the zone of aeration and the zone of saturation.
