Question The unsaturated zone (or zone of aeration) is the rock and sediment in which pore spaces contain mostly air and some water and therefore are not saturated. The unsaturated zone typically starts at the surface and extends downward to the saturated zone. The contact between the saturated and unsaturated zones is called the water table (Figure 1). groundwater=water in zone of saturation porosity=space be 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?Feb 12, 2017 · What Does Zone of Aeration Mean?
