Above the zone of saturation is an area where both air and moisture are found in the spaces between soil and rock particles. This is called the zone of aeration. Water percolates (moves downward) through this zone until it reaches the zone of saturation. The water table is the top of the saturated zone. Where does it come from? ZONE OF SATURATION: The area of a water-bearing formation in which all spaces between soil particles and rock structures are filled with water. ZONE OF AERATION: The area of an unconfined aquifer above the water table where the pore spaces among soil particles and rock formations are filled with air. the bedrock and the upper openings are left in the zone of aeration, only subject to dissolution from running water.

Groundwater is the water which occurs in the zone of saturation where all interconnected voids are filled with water under hydrostatic pressure, while vadose water is the water which occurs in a zone of aeration where interstices are filled partly with water and partly with air (Todd and Mays, 2005). Groundwater is generally less vulnerable to ... The difference between the zone of aeration and the zone of saturation is that in "zone of aeration", the gaps between soil are filled with both air and water and in the "zone of saturation", the gaps are filled with water. [ ] Log in for more information. This answer has been confirmed as correct and helpful.definition. Zone of aeration means a subsurface zone containing water under pressure less than that of the atmosphere, including water held by capillary and containing air or gases generally under atmospheric pressure. This zone is limited above by the land surface and below by the surface of the zone of saturation, e.g., the water table.Subsurface water. Groundwater and soil water together comprise approximately .5% of all water in the hydrosphere. Water beneath the surface can essentially be divided into two zones (Figure \(\PageIndex{3}\)), the unsaturated zone (also known as the "zone of aeration") which includes soil water zone, and zone of saturation which includes ground water.Know the definitions of the following terms: groundwater, porosity, permeability, zone of aeration, water table, zone of saturation, infiltration, aquifer, aquiclude.
