What is gravity spring?
Moreover, what is artesian spring?
Definition of artesian spring. A spring, the water from which issues under artesian pressure, generally through some fissure or other opening in the confining bed that overlies the aquifer.
Secondly, what causes a spring to form?
Springs Form From Aquifers Groundwater is stored in aquifers, which are underground water reservoirs. These aquifers are underneath permeable soil layers, so water easily trickles through the ground into the aquifer. A spring is formed when the pressure in an aquifer causes some of the water to flow out at the surface.
A spring is simply a place where the water from an aquifer flows out of the ground naturally. In a well, one must dig into the ground to reach the aquifer and tap the water supply. In springs, those conditions are already present and on the surface. Some springs only flow during particular times of year.
