That would be an aquifer, which is a layer of permeable rock that can hold water and allow it to flow. Impermeable rock layers above and below the aquifer restrict the movement of water, causing it to accumulate within the aquifer.
A confined aquifer, also known as an artesian aquifer, is bounded above and below by impermeable layers of rock or sediment which prevent water from easily entering or leaving the aquifer. This creates high pressure within the aquifer, causing water to flow upward when a well is drilled into it.
Water under pressure in a confined aquifer is groundwater that is located between impermeable layers of rock or sediment and is under enough pressure that when a well is drilled into it, the water will rise above the top of the aquifer without the need for pumping. This type of aquifer is also known as an artesian aquifer.
A type of well that occurs when a portion of an aquifer is under pressure is known as an artesian well. In this scenario, the aquifer is confined between impermeable layers, allowing water to be naturally pressurized. When a well is drilled into this pressurized aquifer, water can rise to the surface without the need for pumping. Artesian wells are often characterized by their ability to flow freely due to the pressure within the aquifer.
In some ground formations there is an impermeable layer which holds the water beneath it under pressure. In such a case where a well penetrates the impermeable layer, the water rises through the upper layers of the ground and even above ground-surface level
When the pressure of rock layers pressing on an aquifer makes the water in the aquifer rise to the surface without pumping, it is called artesian pressure. This natural pressure occurs when a confined aquifer is sandwiched between impermeable layers, causing the water to flow upward due to the pressure gradient.
Confined acquifer:An aquifer which is sandwiched between two layers of less permeavle material is called confined aquifer.Unconfined acquifer:Aquifers having water table in it is called unconfined aquifer.
That would be an aquifer, which is a layer of permeable rock that can hold water and allow it to flow. Impermeable rock layers above and below the aquifer restrict the movement of water, causing it to accumulate within the aquifer.
A spring is formed when groundwater that flows in an aquifer between two layers of impermeable rock is forced to the surface by an increase in pressure. This happens when the water table intersects the land surface.
artesian well
An artesian well occurs when a portion of an aquifer is confined between impermeable layers and becomes pressurized, causing water to flow naturally to the surface without the need for pumping. This happens when a downward-sloping aquifer is trapped between two impermeable layers, creating enough pressure for the water to rise above the level of the aquifer.
Artesian spring. This occurs when an aquifer is confined between impermeable rock layers, creating pressure that forces the water to rise naturally to the surface without the need for pumping.
A confined aquifer, also known as an artesian aquifer, is bounded above and below by impermeable layers of rock or sediment which prevent water from easily entering or leaving the aquifer. This creates high pressure within the aquifer, causing water to flow upward when a well is drilled into it.

Water under pressure in a confined aquifer is groundwater that is located between impermeable layers of rock or sediment and is under enough pressure that when a well is drilled into it, the water will rise above the top of the aquifer without the need for pumping. This type of aquifer is also known as an artesian aquifer.
An impermeable layer underground that holds groundwater is called an aquifer. Aquifers are underground layers of rock or sediment that are saturated with water and have limited permeability, preventing water from easily flowing through them.
A confined aquifer is surrounded by impermeable layers, restricting water flow and increasing pressure, while an unconfined aquifer has no such restrictions, allowing water to flow more freely and be easily accessed.
