Halite - Science Olympiad - Google

Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporateduring dry seasons, causing a recession in the water level and an increase of salinity content.
