Salt that is used for a variety of industrial and food-related purposes comes primarily from shallow bodies of sea or mineral water and from mining operations dedicated to salt production. The method of production is determined by the location from which the salt is harvested. Location and method also determine the type of salt sold as a final product as well as its intended use.Continue Reading
The three methods of industrial salt production are solution mining, deep-shaft mining and solar evaporation. Most table and industrial salt is produced by solution mining, whereby water is injected into massive deposits of salt forced to the surface of the Earth by tectonic pressures. The water dissolves the salt into a solution, called brine, which is then pumped out and dehydrated at another location.
In deep-shaft mining, or conventional mining, tunnels are dug underground to reach the salt leftover from ancient sea beds, which is then mined like any other mineral. This primarily results in rock salt. The purest salt, however, is harvested through solar evaporation. In warm regions with low rates of precipitation, salt is harvested once a year from shallow ponds and pools evaporated by the sun during the summer. Salt produced in this fashion, called “sea salt,” is a common ingredient in cooking and cosmetics.Learn more about Organic Chemistry
While there is no way to know how many fish are in the sea, the number of fish species in the world's oceans, seas and other bodies of water is estimated to be between 27,300 and 32,000 total as of 2014. This number includes both freshwater and saltwater fish.Full Answer >
Large bodies of water take longer to warm or cool than the land does, so coastal regions generally see lower temperatures during the summer and warmer temperatures during the winter than areas that are further inland. When warm air from the inland areas meets the cool sea air, moisture and water droplets form fog, which is far less common further from the sea.Full Answer >
Metals corrode more quickly near the sea due to the water content in the air and the presence of salt. Metal atoms can react with other elements, becoming charged. When they become charged, they are attracted to water molecules and subsequently dissolve. Salt's electrolyte characteristics speed up the process.Full Answer >
Water dissolves salt by dissociating the ions in salt from each other. Because water is a polar molecule, each of its ends holds a slight positive or negative electrical charge. These ends attract the positive and negative ions in salt and pull them apart from each other.Full Answer >
