Answer:
The process that can lead to the formation of rock salt is called evaporation.
Step-by-step explanation:
Rock salt, also known as halite, is a sedimentary mineral formed by the evaporation of ancient saltwater bodies. When a body of water containing dissolved salt (usually sodium chloride) evaporates, the salts are left behind and eventually crystallize to form rock salt deposits. This process often occurs in arid regions where there is high evaporation and low precipitation, leading to the concentration and subsequent crystallization of salts over time. As the water evaporates, the dissolved minerals come out of solution and accumulate as salt deposits. Over millions of years, these deposits can be buried and compacted to form solid rock salt layers.
