What distinguishes a flowing artesian well from a regular artesian well?

A flowing artesian well is characterized by the natural pressure of underground water that allows it to rise to the surface without the need for pumping. This occurs when the water is contained within an aquifer that is under pressure, creating conditions where it can flow freely when tapped by a well. The distinction of continuous flow is essential, as it indicates that the water is under sufficient pressure to rise above the level of the aquifer it comes from.

In contrast, a regular artesian well may not have this continuous flow feature; instead, it relies on mechanical means, such as pumping, to draw water to the surface. The other options either pertain to factors that can vary independently of the well type or do not accurately describe the unique characteristics of flowing artesian wells.
