  2. Fossil water - Wikipedia

    en.wikipedia.org/wiki/Fossil_water

    Fossil water can potentially dissolve and absorb a number of ions from its host rock. Salinity in groundwater can be higher than seawater. [5] In some cases, some form of treatment is required to make these waters suitable for human use. Saline fossil aquifers can also store significant quantities of oil and [6] natural gas. [7]

  3. Nubian Sandstone Aquifer System - Wikipedia

    en.wikipedia.org/wiki/Nubian_Sandstone_Aquifer...

    The transport of pipe segments for the Great Man-Made River (GMMR) in the Sahara desert, Libya, during the 1980s.A network of pipes that supplies water from the Nubian Sandstone Aquifer System, a fossil aquifer in the Sahara desert of Libya, the GMMR is the world's largest irrigation project.

  4. Groundwater - Wikipedia

    en.wikipedia.org/wiki/Groundwater

    Groundwater is fresh water located in the subsurface pore space of soil and rocks.It is also water that is flowing within aquifers below the water table.Sometimes it is useful to make a distinction between groundwater that is closely associated with surface water, and deep groundwater in an aquifer (called "fossil water" if it infiltrated into the ground millennia ago [8]).

  5. Isotope hydrology - Wikipedia

    en.wikipedia.org/wiki/Isotope_hydrology

    The isotope hydrology program at the International Atomic Energy Agency works to aid developing states to create a detailed portrait of Earth's water resources. [9] In Ethiopia, Libya, Chad, Egypt and Sudan, the International Atomic Energy Agency used radioisotope techniques to help local water policy identify and conserve fossil water.

  6. Natural resource - Wikipedia

    en.wikipedia.org/wiki/Natural_resource

    The water current can be used to turn turbines for hydroelectric generation. The ocean is an example of a natural resource. Ocean waves can be used to generate wave power, a renewable energy source. Ocean water is important for salt production, desalination, and providing habitat for deep-water fishes. There is biodiversity of marine species in ...

  7. Permineralization - Wikipedia

    en.wikipedia.org/wiki/Permineralization

    Permineralization, a type of fossilization, involves deposits of minerals within the cells of organisms. Water from the ground, lakes, or oceans seeps into the pores of organic tissue and forms a crystal cast with deposited minerals. Crystals begin to form in the porous cell walls.

  8. Skeletal changes of vertebrates transitioning from water to land

    en.wikipedia.org/wiki/Skeletal_changes_of...

    The water-based lateral line system was used substantially by these aquatic tetrapods to detect danger from predators. [2] Within the Osteichthyan diversification, there were no changes related to respiration in the transition as can be seen by the nasal region and palatal morphology in elpistostegalid fishes.

  9. Water resources - Wikipedia

    en.wikipedia.org/wiki/Water_resources

    Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...
