The water table is the bottom of the saturated zone is made of nonporous and impermeable rock doesn't exist in dry climates, like deserts rises during periods of high precipitation

Groundwater enters the ground by virtue of gravity. It is found beneath the surface of the ground in the zone of saturation. Above the zone of saturation is the zone of aeration. As water enters the soil, it passes through the water table (area where much of the water is found) and into the zone of aeration where it is filtered by the soil and rock particles. The water table is the bottom of the saturated zone. The filtered water enters the zone of saturation where every pore space between rock and soil particles is saturated with water.

The best answer to the incomplete statement 'The water table...' would be the statement 'is the bottom of the saturated zone. The water table is composed of a water storage at the bottom of the saturated zone under the surface of the earth.
