Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%.
Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation.
Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.

Amman (English:; Arabic: عَمّان ʻammān pronounced [ʕamːaːn]) is the capital and largest city of Jordan and the country's economic, cultural and political centre. With a population of 4,007,526, Amman is the biggest city in the Levant area and the sixth-largest town in the Arab world.The earliest evidence of settlement in Amman is in a Neolithic site known as'Ain Ghazal, where some of the oldest human statues ever discovered dating to 7250 BC were uncovered. During the Iron Age, the city was known as Ammon, home to the Kingdom of the Ammonites. It was called Philadelphia during its Greek and Roman periods, and was finally called Amman during the Islamic period. For much of the middle and early Islamic periods (7th--14th centuries), it served as a centre for the Balqa district of Syria. Afterwards, Amman was a largely abandoned site before the late 19th century when Circassian immigrants were settled there by the Ottoman Empire in 1878. The first municipal council was established in 1909. Amman witnessed rapid growth after its designation as Transjordan's capital in 1921, and after several successive waves of refugees: Palestinians in 1948 and 1967; Iraqis in 1990 and 2003; and Syrians since 2011. It was originally built on seven hills but now spans over 19 hills combining 22 areas, which are administered by the Greater Amman Municipality headed by its mayor Yousef Shawarbeh.
