Quizplus · Accepted Answer

In an artesian well, water flows upward due to pressure from a confined aquifer, which is sandwiched between two impermeable layers of rock or sediment. This pressure causes water to flow freely to the surface without pumping. Therefore, the correct option is C. Options A, B, and D do not accurately describe the characteristics of an artesian well.
