Answer 1

There are two main origins of all salts. Some are from ancient oceans that once covered the earth. As the water retreated and evaporated, it left behind rich salt beds and underground deposits. As geological shifts and volcanic eruptions occurred, strata of salts were trapped between layers of rock and volcanic ash, sealing the deposits from pollutants that were later introduced into the environment. Salt deposits are found and mined on every continent.
The other origin of salt is through water. Seawater is, of course, quite salty, and salt is harvested from it using solar evaporation, either naturally or with the use of technology. Other water sources of salt include landlocked lakes, such as the Dead Sea and the Great Salt Lake in Utah. These are considered "terminal" lakes, meaning that tributaries carry water into them, but there are no outlets carrying water out. The water coming into these contains minerals, among which are salts. Since there are no water outlets, the minerals (and salts) accumulate in the lake and, as water the lake water evaporates, the concentration of minerals increases.
