Zone of Aeration
Water
The comparatively dry soil or rock located between the ground surface and the top of the water table. The zone of aeration is not saturated with water because its pores are filled partly by air and partly by water.
The locus of points just above the water table where soil pores may either contain air or water. This is also called the vadose zone.
