Detailed explanation-1: -As we dig deeper, the groundwater is stored between layers of hard rock below the water table. This deposit of water is called an aquifer. Groundwater can be extracted from aquifers using a water well.

Detailed explanation-2: -Groundwater fills in all the empty spaces underground, in what is called the saturated zone, until it reaches an impenetrable layer of rock. Groundwater is contained and flows through bodies of rock and sediment called aquifers.

Detailed explanation-3: -C-horizon consists of small pieces of rocks broken down due to weathering. The groundwater gets collected in the C-horizon.

Detailed explanation-4: -Groundwater can also be extracted through a well drilled into the aquifer. A well is a pipe in the ground that fills with groundwater. This water can be brought to the surface by a pump. Shallow wells may go dry if the water table falls below the bottom of the well.

Detailed explanation-5: -The alluvial tract of the Gangetic plain, which extends over 2000 km across central and northern India has the best potential for groundwater extraction in the country.
