Question

Quizplus · Accepted Answer

Most dissolution of bedrock to form caves takes place just below the water table because this is where groundwater is most abundant and the water reacts with the rock, dissolving it to create cavities and passages. Above the water table, there is not enough water to cause significant dissolution, and greater than 10 m below the water table, the pressure from the overlying rock can make it too difficult for water to enter and dissolve the rock.
