they are harder and not easily broken.
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 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.
This process is called artesian flow. It occurs when the pressure from surrounding rock layers forces water in an aquifer to rise above the level of the aquifer, sometimes to the Earth's surface, without the need for pumping.
In an artesian formation, the rock layers are inclined or tilted, creating a confined aquifer with pressure that can cause water to rise naturally to the surface. In an ordinary aquifer, the rock layers are typically horizontal, allowing water to flow more freely without the same pressure dynamics as in artesian formations.
An artesian formation is a type of aquifer in which water is trapped between layers of impermeable rock or sediment, causing the water to be under pressure. This pressure can cause the water to flow to the surface without the need for pumping, creating artesian wells.

For an artesian well to form, there must be a sloping aquifer that is bounded above and below by impermeable layers, creating pressure on the water in the aquifer. Additionally, a well drilled into this confined aquifer will cause the pressured water to flow upwards to the surface without the need for mechanical pumping.
An artesian basin is a geological formation that contains water-bearing layers of rock or sediment, while an artesian well is a well drilled into an artesian basin that taps into a pressurized aquifer, allowing water to flow to the surface without the need for pumping. Essentially, an artesian well is a man-made structure that utilizes the water stored in an artesian basin.
When the pressure of rock layers pushes water from an aquifer up to the Earth's surface, it is called artesian flow. This natural process occurs when there is enough pressure in the aquifer to force the water upward through a well or borehole without the need for a pump.
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.
Conditions necessary for an artesian well are an inclined aquifer sandwiched between impervious rock layers above and below
