Answer: Experiment.
Explanation:
Suppose that we have two related variables, A (independent) and B (dependent)
We could design an experiment where we can manipulate the value of A at will, and we also can observe how the variable B changes.
This is called an experiment, where the objective is to see how the variable B is related to the variable A, and then try to make a model that explains this relationship.

Explanation:
An aquifer is an underground layer of water-bearing permeable rock or rock fractures or. The system shows two aquifers with one aquitard. Some abundant small openings store a large quantity of water. Groundwater may exist in underground rivers or underground cave systems where water flows freely underground. If the impermeable area overlies the aquifer, pressure could cause it to become a confined aquifer.
