The valley is formed and developed under the action of flowing water erosion: the water flow carries the sediment erosion to cut the valley down; The side erosion of the water flow causes the valley slope to peel back, including the chip erosion, trench erosion and block collapse on the valley slope; Trace erodes the valley upward and lengthens it. Category 3 erosion methods are often carried out simultaneously, but at different times and locations. The development of the valley is influenced by climate and tectonics.
