GEOLOGY

Detailed explanation-1: -An artesian well is a well that brings groundwater to the surface without pumping because it is under pressure within a body of rock and/or sediment known as an aquifer.

Detailed explanation-2: -Pressure from the water’s weight (hydrostatic pressure) forces water to the surface of a well drilled down into the aquifer; the pressure for the steady upflow is maintained by the continuing penetration of water into the aquifer at the intake area.

Detailed explanation-3: -Groundwater in aquifers between layers of poorly permeable rock, such as clay or shale, may be confined under pressure. If such a confined aquifer is tapped by a well, water will rise above the top of the aquifer and may even flow from the well onto the land surface.

Detailed explanation-4: -An artesian well is any formation in which groundwater rises on its own under pressure.

Detailed explanation-5: -An artesian well is created by water that flows across a patch of degraded land, then passes into porous rock, such as sand, gravel, or limestone. This porous substance is situated within an impenetrable, non-porous rock layer, which creates a high amount of pressure.
