Freshwater represents only about three percent of all water on Earth and freshwater lakes and swamps account for a mere 0.29 percent of the Earth's freshwater. Twenty percent of all fresh surface water is in one lake, Lake Baikal in Asia. Another twenty percent (about 5,500 cubic miles (about 23,000 cubic kilometers)) is stored in the Great Lakes.

May 20, 2022Another source of unconventional natural gas is geopressurized zones. Geopressurized zones form 3,000-7,600 meters (10,000-25,000 feet) below the Earth's surface. These zones form when layers of clay rapidly accumulate and compact on top of material that is more porous, such as sand or silt.

soil liquefaction, also called earthquake liquefaction, ground failure or loss of strength that causes otherwise solid soil to behave temporarily as a viscous liquid. The phenomenon occurs in water-saturated unconsolidated soils affected by seismic S waves (secondary waves), which cause ground vibrations during earthquakes. Although earthquake shock is the best known cause of liquefaction ...
