Which of the following describes the zone of saturation?
when the pores are empty within the rocks and soil
when the pores are completely filled in the rocks and soil
the area where water is discharged back to the surface
the location of the water table in the groundwater system

when the pores are completely filled in the rocks and soil

Explanation:

The zone of saturation is part of the divisions of ground water systems. It is the zone in which the pore spaces within the rock are completely filled with water.

The zone of saturation is where the aquifer lies in a body of water and it is the ground water prospect. Pore spaces can also be filled with hydrocarbons.

Above the zone of saturation is the water table. The water table defines the upper layer of the zone of saturation above which the pore spaces are filled with gas or no water can be found.
