GEOLOGY

Detailed explanation-1: -Excess rainwater percolates into the soil and rock beneath the earth’s surface accumulating in zones of saturation called aquifers. A well is a hole drilled into the aquifer from which a small portion of the groundwater can be pumped to the surface for man’s use.

Detailed explanation-2: -The top of the saturated zone is called the water table (Diagram 1). The water table may be just below or hundreds of feet below the land surface.

Detailed explanation-3: -zone of saturation, saturated zone) is the area in an aquifer, below the water table, in which all pores, fractures, and cavities (including karst caves) are filled with water.

Detailed explanation-4: -ZONE OF SATURATION: The area of a water-bearing formation in which all spaces between soil particles and rock structures are filled with water. 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.
