Ground Water and Aquifers verified already passed

Ground Water and AquifersAquifer - correct answer A natural underground area where large quantities of ground water fill the spaces between rocks and sediment. Confined Aquifer - correct answer An aquifer overlain by one or more layers of impermeable rock or soil (aquitard/confining layer) that restrict water to within the aquifer. Confining Layer - correct answer An underground layer over an aquifer that is impermeable or significantly less permeable than the aquifer below it. It helps protect the aquifer from contamination and is usually made of rock and/or clay. Also called an "aquitard." Conserving Water - correct answer Not wasting water. Porous - correct answer Full of pores (small spaces). Water can easily pass through it. Protecting Water - correct answer Keeping water clean. Saturated Zone - correct answer An underground layer or area where water fills most of the pores (spaces) in the soil and rock. Unconfined Aquifer - correct answer An aquifer that is not overlain by a layer of impermeable rock or soil. Unsaturated Zone - correct answer An underground layer or area where air fills most of the pores (spaces) in the soil and rock. Water Table - correct answer The top of an unconfined aquifer. Impermeable - correct answer not permitting water or other fluid to pass through.
