Oases are formed from underground rivers or aquifers such as an artesian aquifer, where water can reach the surface naturally by pressure or by man made wells. Occasional brief thunderstorms provide subterranean water to sustain natural oases, such as the Tuat. 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.credited to wikipedia and flickr users: artour_a, rasielcom, noushynoo, ccullen222, elmnopo, missmarmelade, akapadia76, jries, gazapofera, feke
