Quizplus · Accepted Answer

The unsaturated zone refers to the area between the soil-water belt (where soil pores are filled with both air and water) and the water table (where all pore spaces are saturated with water). It is also known as the vadose zone or the zone of aeration. The saturated zone (choice A) refers to the area below the water table, where all pore spaces are filled with water. An aquiclude (choice C) is a layer of impermeable material (such as clay) that restricts or prevents the flow of water between aquifers. An aquifer (choice D) is a layer of permeable material (such as sand or gravel) that can store and transmit groundwater. An artesian well (choice E) is a well drilled into an aquifer that is under enough pressure to cause the water to flow to the surface without pumping.
