GEOLOGY

Detailed explanation-1: -A well is human-made hole that is dug or drilled deep enough to intersect the water table. Wells are usually used as a source for groundwater. If the well is dug beneath the water table, water will fill the open space to the level of the water table, and can be drawn out by a bucket or by pumping.

Detailed explanation-2: -The saturated area beneath the water table is called an aquifer, and aquifers are huge storehouses of water. In our sand hole example, you have essentially dug a “well” that exposes the water table, with an aquifer beneath it.

Detailed explanation-3: -Groundwater is water that is stored or travels through the materials beneath the ground surface. Groundwater occupies fractures in rock and the pore space in soils between sand and gravel particles below the ground surface, as illustrated in this image.

Detailed explanation-4: -ZONE OF AERATION: The area of an unconfined aquifer above the water table where the pore spaces among soil particles and rock formations are filled with air.

Detailed explanation-5: -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.
