The process you're describing—where evaporation of water leaves behind crystals that expand and cause the rock to break—is known as salt wedging. This occurs when saline water evaporates, leaving behind salt crystals that expand and exert pressure on the surrounding rock, leading to weathering and fragmentation.
The evaporation of water within rocks, that leaves behind expanding crystals that cause breaking, is know as?
hydrolysis
ice wedging
salt wedging
chemical weathering
