GEOLOGY

Detailed explanation-1: -A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table.

Detailed explanation-2: -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-3: -water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it.

Detailed explanation-4: -The water travels down through the permeable rock until it reaches a layer that does not have pores; this rock is impermeable (Figure below). This impermeable rock layer forms the base of the aquifer. The upper surface where the groundwater reaches is the water table.

Detailed explanation-5: -Groundwater. Groundwater is water that has infiltrated the ground to fill the spaces between sediments and cracks in rock.
