Quizplus · Accepted Answer

An impermeable layer of rock or sediment is referred to as an aquitard, which is a layer that restricts or limits groundwater flow. A confined aquifer is a layer of water-bearing rock or sediment that is trapped between two impermeable layers, while an unconfined aquifer is a layer that is not trapped between impermeable layers. The unsaturated zone is the region of soil and rock above the water table where the pores are not fully saturated with water.
