    • The vegetated area around it is known as A permanent source of water in a desert and Oasis

    • An exotic river has its source in a rainy area beyond the margins of the desert

    • Examples of exotic rivers are

    • - The Nile in Egypt, The Tigris and the Euphrates in Iraq, The Indus in Pakistan and The Colorado in the USA

    • Channels that are dry except during the rainy season are called wadis in Arabic-speaking countries.

    • Although the surface of the channel is dry, water is present underground and can be obtained using wells; in some regions, natural springs also supply water.

    • As in the case of exotic rivers, the source of water in natural springs too lies outside the desert.
