What Is A Salt Pan?
Salt is in important compound formed by the neutralization reaction of an acid and base. Salts are made up of cations and anions making the compound electronically neutral. Salt comes in several varieties and can be hydrolyzed to produce alkaline salt or acidic salt. Neutral salts are neither acidic nor basic. Most salts are transparent or clear in color but can also exist in many other colors including yellow, orange, red, blue, and purple. Compound salt or table salt is traditionally used to season or preserve or preserve foods. Salts can be formed on a large expanse of land to form Salt pan
Salt flat or salt pan is a large area of land covered with salt and other minerals and often shines or looks white because of the presence of salt. Salt pans form in the desert and other arid areas where large water bodies have dried up over thousands of year leaving behind salt and other minerals as remnants. Salt pans are found around the world, especial in countries characterized by vast deserts and arid conditions. However, some of the largest salt pans around the world are found in Bolivia and the states of Utah and California.
Formation Of Salt Pan
There are three basic things needed for a salt pan to be formed. These include the source of salt, an enclosed drainage basin to keep the salt from washing away, and an arid or desert climate condition with higher evaporation than precipitation for the salt to be left behind when the water dries up. An arid climate is the most important condition for the formation of a salt pan. In desert places, there are few large rivers with several meandering streams because of the inadequate water. As a result, many lakes in the desert lack outlets such as streams. The enclosed basins ensure that the lakes do not form an outlet. The lack of rainfall in deserts ensures that the evaporation rate is higher than precipitation which leads to the formation of salt pans. Also, the enclosed drainage basins must contain salt and other minerals for the salt flat to be formed. Some of the common minerals found alongside the salts include gypsum and calcium. Halite is a type of salt that is common in most of the salt pans.
Examples Of Salt Pans
Large salt pans are found around the world in places such as Africa, South America, and the US. The largest salt flat in the world is located in Potosi and Oruro in Bolivia. The Salar de Uyuni covers an area of about 4,000 sq miles and is located at an elevation of 3,656 meters. The Salar de Uyuni is a large breeding ground for pink flamingos. The Bonneville salt pans are located in the state of Utah covering an area 45 square miles and are remnants of Lake Bonneville that existed 17,000 years ago. The Etosha pan located in Etosha National Park in Namibia is also a prominent salt pan in Africa. The Death Valley National Park in California is also home to some of the largest salt pans. The Badwater Basin Salt Pans cover an estimated area of 200 square miles.
Uses Of Salt Pans
Salt pans are important sources of minerals and salt characterized by a lot of mining activities. Other human activities and development such as calibrating of satellite and speed recording are common on salt pans because of their large expanse. The pans are also important travel routes.
