Frost weathering of rocks in the presence of salts‐a review
Abstract In many temperate and cold regions, rocks containing salt in solution are subject to frost action. Although the salts depress the freezing point of water, their most common effect at subzero temperatures is to increase the intensity of rock breakdown. Different mechanisms to explain why sal...
