Question

Quizplus · Accepted Answer

An unconfined aquifer is a body of permeable, saturated rock or sediment that can be directly accessed by water percolating from the ground surface. Choice A, aquitard, refers to an impermeable layer that restricts the flow of water between aquifers. Choice B, confined aquifer, is a permeable rock or sediment layer that is sandwiched between two aquitards and is under pressure, resulting in the water level in the aquifer being higher than the top of the aquifer. Choice D, unsaturated zone, refers to the portion of the ground where the pores in the rock or sediment are not filled with water but rather a mixture of water and air.
