In geography, an oasis (plural: oases) is an isolated area of vegetation in a desert, typically surrounding a spring or similar water source. The Sahara (الصحراء الكبرى aṣ-ṣaḥrā´ al-kubra, "The Great Desert" is the world's largest hot Desert and the world's second largest Geography (from Greek γεωγραφία - geografia) is the study of the Earth and its lands features inhabitants and phenomena A desert is a Landscape or region that receives very little precipitation. A spring is a point where Groundwater flows out of the ground and is thus where the Aquifer surface meets the ground surface Oases also provide habitat for animals and even humans if the area is big enough.

The location of oases has been of critical importance for trade and transportation routes in desert areas. Caravans must travel via oases so that supplies of water and food can be replenished. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route. For example, the oases of Awjila, Ghadames and Kufra, situated in modern-day Libya, have at various times been vital to both North-South and East-West trade in the Sahara desert.

Oases are formed from underground rivers or aquifers such as the Artesian aquifer, where water can reach the surface naturally by pressure or by man made wells. The city of Ica is the capital of the Ica Region in southern Peru. See Great Artesian Basin for the water source in Australia An artesian aquifer is a confined aquifer containing Groundwater Occasional brief thunderstorms provide subterranean water to sustain natural oases, such as the Tuat. For other meanings see Tuat and similar (disambiguation. Tuat ("Tawat" or in French "Touat" is a Berber name Substrata of impermeable rock and stone can trap water and retain it in pockets; or on long faulting subsurface ridges or volcanic dikes water can collect and percolate to the surface. Any incidence of water is then used by migrating birds who also pass seeds with their droppings which will grow at the waters edge forming an oasis.

People who live in an oasis use every bit of land. Libya ( ليبيا ar-Latn Lībiyā; Libyan vernacular: Lībya; Amazigh:) officially the Great Socialist People's Libyan Arab The Sahara (الصحراء الكبرى aṣ-ṣaḥrā´ al-kubra, "The Great Desert" is the world's largest hot Desert and the world's second largest Water has to be used carefully; the fields must be irrigated to grow plants like dates, figs, olives, and apricots. The most important plant in an oasis is the date palm which forms the upper layer. These palm trees provide shade for smaller trees like peach trees, which form the middle layer. Plants like potatoes, onions, carrots, and other vegetables form the lowest layer. The date palms do more than protect other plants from the burning sun - all parts of an oasis are very important for the people. By growing plants in different layers, the farmers make best use of the soil and water.
