The correct answer is "aquifer." An aquifer is an underground layer of porous and permeable rock that is capable of storing and transmitting water. To identify this answer, you can use the process of elimination by considering the other options:
- Deposit: A deposit typically refers to a layer of material that has been laid down or accumulated, such as a geological or mineral deposit, but it does not specifically describe a layer that holds water.
- Subsidence: Subsidence is the sinking or settling of the Earth's surface, often caused by the extraction of underground fluids or the collapse of underground structures. While subsidence can be related to underground water, it does not directly describe a layer of porous and permeable rock that holds water.
- Reservoir: While a reservoir can store water, it typically refers to a man-made structure or artificial lake that is created to hold water for human use, such as for drinking water supply or irrigation. It is not specifically associated with a layer of rock but rather a constructed storage space.
Therefore, the only option that accurately describes an underground layer of porous and permeable rock that holds water is "aquifer."
