When the river flows through the desert, it seeps into the sand and becomes groundwater. Groundwater flows along the impermeable rock layer to the desert low-lying areas, that is, gushing out of the ground. In addition, the rainwater in the distance seeps into the ground, and can also merge with the groundwater to flow to the low-lying areas of the desert. Or because of the crustal movement, the impermeable rock fracture is caused, so that the groundwater flows along the fissure to the low-lying desert area and flushes out of the ground.
With water in the low-lying areas, all kinds of organisms emerge as the times require, develop and multiply, thus forming an oasis. Oasis in the desert, rich in water, fertile soil, suitable for the growth of crops and other plants. Oasis often forms a unique beautiful scenery.
