    Areic Basin, Endorheic Basin and Exorheic Basin

    Uploaded by

    There are three types of basins: 1. Exorheic basins have outlets and their waters flow into seas or other bodies of water. They make up seven of the major drainage basins worldwide. 2. Endorheic basins are internally drained with no outlets, so their waters evaporate or seep into the ground instead of flowing into seas or lakes. Examples are the Aral Sea and Caspian Sea. 3. Areic basins also have no outlets, but are even more isolated as their waters completely disappear through evaporation or infiltration into the ground. The Sahara desert contains many areic basins.

    Diference:

    In of a lake or basin|lang=en terms the difference between exorheic and endorheic is that
    exorheic is (of a lake or basin) externally drained; having one or more outlets while endorheic is (of
    a lake or basin) internally drained; having no outlet.

    As adjectives the difference between exorheic and endorheic is that exorheic is (of a lake or basin)
    externally drained; having one or more outlets while endorheic is (of a lake or basin) internally
    drained; having no outlet.

    Areic basin

    Finally, the arreic basins are those hydrographic basins whose waters do not flow into seas or
    lakes, as they end up evaporating or infiltrating into the ground until they disappear. Generally,
    these basins occur in areas where the climates are arid or desert, an example is the basin located
    in the Qattara depression, located in the Libyan desert.

    Exorheic basin

    An exorheic basin is an "open" system of water circulation on the earth's surface, whose main
    collecting and draining rivers flow into the sea, i.e. outside the territory. There are seven exorheic
    basins in the world, corresponding to the seven major oceanic water masses and two of the
    largest seas.

    Areic basins are watersheds that do not flow into any body of water, neither into the sea nor into
    lakes, as their waters evaporate into the atmosphere or seep into the ground before reaching a
    drainage network.

    They are less common than exorheic and endorheic basins. Examples include the streams and
    watercourses of the central Patagonian plateau, or many streams and runoffs of the Sahara and
    other desert areas.

    Endorheic basin
    An endorheic basin (from Greek ἔνδον, éndon, "within" and Greek ῥεῖν rheîn, "to flow") is a closed
    drainage basin that retains water and does not allow its outflow to other external bodies of water,
    such as rivers or oceans, but converges into lakes or marshes, permanent or seasonal, which are
    balanced by evaporation. These basins may also be called closed or terminal basins or internal
    drainage systems.

    Normally, water that has accumulated in a drainage basin eventually exits through rivers or
    streams at the Earth's surface or by subway diffusion through permeable rocks, eventually ending
    up in the oceans. However, in an endorheic basin, the rain (or other precipitation) that falls in it
    does not flow out, but can only leave the drainage system by evaporation and seepage. The
    bottom of such a basin is usually occupied by a salt lake or a saline.

    Endorheic regions, unlike exorheic regions, which drain into the ocean following geologically
    defined patterns, are closed hydrological systems. Their surface waters drain to terminal inland
    locations, where the water evaporates or seeps into the ground, with no access to discharge into
    the sea. Endorheic water bodies include some of the world's largest lakes, such as the Aral Sea and
    the Caspian Sea, the world's largest body of saline water isolated from the ocean.
