The permeability and porosity of an aquifer is very high, air and pretty much any liquid can pass trough it with ease. Where as shale has very little porosity making it virtually impossible for air or liquid to pass through.
A big factor is compaction. Another factor is clay content. I noticed that salinization affects permeability, too. The fields in Iraq have been irrigated for millennia. When it rains, the first few inches of dust turn to thick, sticky mud and the soil beneath remains dry.
Another name for the zone of saturation is phreatic zone.They both describe the area in an aquifer, which is the underground layer of water-bearing permeable rock or some other forms of unconsolidated material such as sand and gravel, where water can be extracted using a well.Related links and further reading:Click here for further information on the zones.Click here for further information on aquifers.Related video:
ground water Groundwater is located beneath the soil surface. A sustainable amount of ground water creates an aquifer. The point at which the soil and rocks become completely saturated is the water table. Groundwater will flow to the surface naturally. The study of groundwater is hydrogeology.
The asthenosphere is part of the upper mantle and it is beneath the lithosphere. Beneath the asthenosphere and mantle is the outer core and beneath that is the inner core.
Melted rock beneath the earth is called magma.
The relationship between density and porosity is an indirect proportionality.That is, the higher the density of a rock, the lower will be the porosity of that rock.In a more explicit way, the weight of over-lying rocks increase the density of the rock beneath, which in turn decreases the amount of pore spaces (porosity) of the rock through processes such as compaction, cementation, etc. Posted by Nwigwudu Ikechukwu.
a water-bearing stratum of permeable rock, sand, or gravel
According to newarkadvocate.com, "Pataskala gets its drinking water from an aquifer located more than 100 feet beneath the ground. It is recharged [. . .] by rain and water flowing from the South Fork of the Licking River."

Water in rocks (or other porous material) below the ground is called ground water.
The Nazca Plate is subducting beneath the South American Plate, causing the uplift of the Andes Mountains. This geologic activity has created a series of aquifers in the region as water seeps through the fractured rock layers of the mountains, filling underground reservoirs known as aquifers.
Beneath.
Beneath is an adverb.
more beneath, most beneath
