Geological and Hydrological Conditions Desert oases form through unique interactions between groundwater and surface geology. They typically occur where underground aquifers intersect the surface, creating natural springs in otherwise arid landscapes. These water sources often emerge along fault lines or where impermeable rock layers force groun
