Quizplus · Accepted Answer

An aquiclude is a layer of rock or sediment that does not allow water to flow through it, therefore it is a layer through which groundwater cannot run or flow. Phreatic refers to the zone where water fills all the pore spaces in soil or rock, aquifer is a layer of rock or sediment that contains and transmits groundwater, and vadose refers to the zone above the water table where pore spaces contain air and may also contain water. Therefore, neither A, B, nor D fits the definition of a layer through which groundwater cannot flow.
