Quizplus · Accepted Answer

A confined aquifer is formed when a lower-permeability layer overlies a higher-permeability layer, creating a confined space that traps water. In sequence B, the high-permeability sandstone layer (H) is sandwiched between two low-permeability shale layers (L), which would create the conditions for a confined aquifer.
