Zone of aeration.

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 main components of this region are the soil and rocks. Their pores are at times partly filled with water and air, and aeration occurs when the air and water mix or come into close contact.1. The zone of aeration is located immediately beneath the root-zone. The zone of saturation lies below the zone of aeration. 2. The soil and rocks in the zone of aeration have pores which are partially filled with water and air. The zone of saturation comprises rocks and soil whose pores are saturated with water. 3.Rain that falls on the surface seeps down through the soil and into a zone called the zone of aeration or unsaturated zone (also called the vadose zone), where most of the pore spaces are filled with air.
