Water in the ground is an intricate part of the water cycle. After rain soaks into the ground it begins to move (according to gravity and pressure). For people, one very valuable reservoir of water underground are called "aquifers". Simply, aquifers are layers and areas of rocks below ground where all the cracks ... InstagramOverview You can't see it, but a large portion of the world's freshwater lies underground. It may all start as precipitation, but through infiltration and seepage, water soaks into the ground in vast amounts. Water in the ground keeps all plant life alive and serves peoples' needs, too.Non-renewable water resources are groundwater bodies (deep aquifers) that have a negligible rate of recharge on the human time-scale and thus can be considered non-renewable. ...
