The zone of aeration
(iv) Saturation zone: In the zone of saturation all the interstices are filled with water under hydrostatic pressure. The zone of saturation is bounded at the top by either a limiting surface of saturation called a water table or overlying impermeable strata and extends down to underlying impermeable strata.Study with Quizlet and memorize flashcards containing terms like Stalactites and stalagmites form when a cave is? -just beginning to dissolve -in the zone of aeration -in the zone of saturation -beneath the zone of saturation, True or False; The formation of karst topography requires the action of groundwater on soluble rocks at or near the surface?
