GENERAL GEOLOGY

Detailed explanation-1: -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-2: -Groundwater can be obtained by digging and drilling of wells. These are the two ways by which people obtain groundwater. Wells are basically wide openings from which water can be pulled out using a pulley and in case of drilled wells a different mechanism is used to pull water upwards.

Detailed explanation-3: -Groundwater is obtained, when the earth absorbs the water from the surface and stores it below the ground. We dig wells and tubewells to gain access to the groundwater.

Detailed explanation-4: -Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.

Detailed explanation-5: -Groundwater occurs in the saturated soil and rock below the water table. If the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water.
