Final answer:
Salt wedging is of slight consequence in humid regions because the consistent presence of moisture limits the evaporation that is necessary for salt crystal formation and growth.
Step-by-step explanation:
Salt wedging is of slight consequence in humid regions (E). Salt wedging is a physical weathering process where salt crystals grow and expand in the cracks and pores of rocks, eventually leading to the breaking apart of the rocks. This process is accelerated in arid regions where there are high levels of evaporation and dry conditions, which allow for the salt crystals to form and grow. However, in humid regions, the consistent presence of moisture limits the evaporation necessary for salt crystal growth, thus making salt wedging a less significant geological process in these areas.
