GEOLOGY

Detailed explanation-1: -Groundwater is the water present beneath Earth’s surface in rock and soil pore spaces and in the fractures of rock formations.

Detailed explanation-2: -Groundwater is water that exists underground in saturated zones beneath the land surface. The upper surface of the saturated zone is called the water table.

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: -The main source of groundwater is the rain. The rainwater and water from other sources such as rivers, lakes and ponds, seeps through the ground and fills the empty spaces between the soil and the rocks below the earth. Handpumps or tube wells are used to pump out ground water.
