Final answer:
The Unsaturated Zone contains both water and air, but not completely saturated with water; water in this zone is referred to as Soil Moisture.
Step-by-step explanation:
The Unsaturated Zone contains both water and air, but not completely saturated with water; water in this zone is referred to as Soil Moisture. Rocks and soil just beneath the land's surface are part of the unsaturated zone, and pore spaces in them are filled with air. Once the water table is reached, then rocks and soil pore spaces are filled with water, in the saturated zone.
