Answer:
Water table and saturation zone
Step-by-step explanation:
Ground water is the reservoir of liquid fresh water which is found in porous rocks, aquifers and sediments with water in between. Slope of land, local climate, type of rock at the surface, land use area, vegetation cover and water retention are the factors which determines how much water will enter the groundwater in a region. The layers of ground water includes surface layer, zone of aeration, water table and zone of saturation.
