The top level of groundwater in an aquifer is called the water table.
A cave is a void (hole) in the ground. An aquifer is a region of water-permeable rock that holds groundwater; it may (or may not) contain caves.
An aquifer transmits ground water freely.

Particles in an aquifer, such as sand, silt, and clay, significantly influence its porosity by determining the amount and size of the spaces between them. Larger particles, like coarse sand or gravel, typically create larger voids, leading to higher porosity and enhanced water flow. In contrast, smaller particles, such as clay, fill these voids and reduce overall porosity. Thus, the composition and arrangement of particles are crucial in defining an aquifer's ability to store and transmit groundwater.
For water to recharge an aquifer, it must pass down through a zone of aeration into the zone of saturation, where the water is stored. The "line" that separates the two zones can be said to be the level of the water table.
