Question

Difference between zone of aeration and saturation

Answer 1

The phreatic zone, or zone of saturation, is the area in an aquifer, below the water table, in which relatively all pores and fractures are saturated with water. The phreatic zone defines the lower edge of the vadose zone.

By definition, the zone of aeration is layer of Earth where the pores and cracks are filled with air and water. It is sub-earthen region that exists between the Earth's surface and water table. This zone mainly comprises porous soil
