摘要
Mars gullies, the very young features exposed on crater rims and sand dunes, are studied in detail using 15 HiRISE images and 107 MOC images in this research, and the hypotheses of gully origination are examined. The results support the hypothesis that the gullies were formed by the erosion of liquid water that carried sand particles. And the existence of polygonal shape on crater walls suggests that water ice maybe located on Mars subsurface, which can melt to liquid water and produce gullies.
