Where Does Salt Wedging Occur?

Salt wedging typically occurs in an estuary along a salinity gradient when a fresh body of water such as a river meets, but does not mix with saltwater from an ocean or sea. The rate of freshwater runoff from a river into an estuary is a major determinant of salt wedge formation.

Where is salt wedging most likely to occur?

Salt wedging occurs when salts crystallize out of solution as water evaporates. As the salt crystals grow, they apply pressure to the surrounding rock weakening it, until it eventually cracks and breaks down, enabling the salt crystal to continue growing. Salt wedging is most common in drier climates, such as deserts.

Where does wedging occur?

Ice wedging breaks apart so much rock that large piles of broken rock are seen at the base of a hillside, as rock fragments separate and tumble down. Ice wedging is common in Earth's polar regions and mid latitudes, and also at higher elevations, such as in the mountains.
