Detailed Description

Your table salt might have come fron an evaporation pond

People all over the world use low-tech techniques to obtain the valuable resource salt. Really, take some ocean water, put in it a pan, hopefully in the sun, and wait for the water to evaporate. 

Of course, large-scale salt evaporation needs to happen to supply the world with the mounds of salt people use all the time. This picture shows a "salt farm" in India.
