Salt wedging is a weathering process which is unimportant in humid regions.

Question

Quizplus · Accepted Answer

Salt wedging occurs when saltwater enters cracks in rocks and then evaporates, leaving behind salt crystals that grow over time and expand the cracks. This process is only significant in arid or semi-arid regions where evaporation rates are high and there is little rainfall to flush out the salt. In humid regions, other forms of weathering such as freeze-thaw and chemical weathering are more significant.
