Salt weathering refers to the physical weathering of the decomposition or shedding of particles on the surface of rock outcrops caused by the expansion of salt crystals in the pores of rocks. Its geomorphology shows the formation of weathering cavities of different sizes. The phenomenon of salt weathering is more obvious in arid regions and seashores in the inland, which is a common physical weathering effect on the land. Geomorphology plays an important role in shaping the process, however, it has been ignored and misunderstood by the geoscience community, and is interpreted as the result of other effects such as wind erosion or water erosion.
