Quizplus · Accepted Answer

An aquiclude is a body of rock or soil that is so impermeable to water that it acts as a barrier to the flow of groundwater. This characteristic distinguishes it from an aquifer, which is permeable and can store and transmit groundwater. Aquanaut, sandstone, and conglomerate do not fit the definition of a material lacking permeability; sandstone and conglomerate are types of rock that can vary in their permeability, and aquanaut is unrelated to the concept of permeability in geological terms.
