How Is Rock Salt Formed? | Sciencing

Rock salt is found in old ocean sea beds that have long ago dried up. The compound originates from a body of sea water that undergoes an intense evaporation process, leaving behind large rings of sea salt. Then through the long process of geologic aging, the salt layers are covered with marine sediments.
