The correct answer is: D. confined groundwater
Confined groundwater is groundwater that is trapped between two impermeable layers of rock or sediment. The pressure of the water in the confined aquifer is greater than the atmospheric pressure, which causes the water to rise to the surface. This type of aquifer is often used for drinking water and irrigation.
Unconfined groundwater is groundwater that is not trapped between two impermeable layers. The water in an unconfined aquifer is in contact with the atmosphere, which means that the pressure of the water is equal to the atmospheric pressure. This type of aquifer is often used for drinking water and irrigation.
An artesian well is a well that taps into a confined aquifer. The water in an artesian well rises to the surface without the need for pumping, because the pressure of the water in the aquifer is greater than the atmospheric pressure.
