Detailed explanation-1: -A water table describes the boundary between water-saturated ground and unsaturated ground. Below the water table, rocks and soil are full of water. Pockets of water existing below the water table are called aquifers. An area’s water table can fluctuate as water seeps downward from the surface.

Detailed explanation-2: -The upper surface of this water-filled area, or “zone of saturation", is called the water table. The saturated area beneath the water table is called an aquifer, and aquifers are huge storehouses of water.

Detailed explanation-3: -The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock. Water pressure and atmospheric pressure are equal at this boundary.

Detailed explanation-4: -This rock wall represents an “outcrop” (or location where the rock intersects the land surface) of an aquifer. The point where the ground water emerges into view is called a “seep” or “spring".

Detailed explanation-5: -Three examples of the water table aquifers are the Ogallala aquifer in the United States of America, the Great Artesian Basin in Australia, and the Lotikipi Basin Aquifer in Kenya.
